Would it be beneficial to learn linear algebra before calculus?

I've had limited experience with linear algebra, but the algebraic concepts have helped me enormously in solving equations. Solving systems of equations is much, much easier using matrices than basic algebraic methods. So, I assume the more linear algebra one knows would make the algebra part of Calculus easier, which is the most difficult part of Calculus.

So, would one run into any problems learning linear algebra before calculus? Would it be beneficial?

Here's how many hours(without breaks) it took me to finish algebra 1 and geometry on Khan Academy.

Do you like statistics, data and stuff? I do :) I wasn't super terrible at math in middle and high-school, but to get B was an achievement. I still suck at math now. Never liked it. Then barely managed to enroll to university and get 100% scholarship. It wasn't hard, it's no big deal here in Kazakhstan(not like in the US). Every my classmate got it. I don't know a proper name of my major in English but it's something about industrial automation. I'm russian btw. Also started learning English 2 years ago. And now I'm halfway through the graduation, barely keeping up with my classmates. I'm in bottom 1/3. Now I can learn stuff in English and it's much more fun and much more content available than in my mother tongue. Now I decided to kill my fear of math and improve my math foundation. That's why I chose Khan Academy. Then I will use openstax books. So, as a result, I figured out that I learned math on Khan Academy more than in all 11 years of school combined.

TL;DR my math background

Can Geometric/Clifford algebra do everything that matrices can?

Clifford algebra has elegant operations for reflections, rotations, etc. It generalizes vectors, quaternions, spinors, complex numbers as sub-algebras of a single system (Only this reason should be enough to prefer them even if they don't bring anything new to the table). It is proposed as an alternative to linear algebra. But are these multivector sub-algebras sufficient to do any arbitrary linear transformation that matrices can do?

The title is self explanatory. I took a class on applications of boolean algebra to computer architecture this last semester and I was wondering how and if this knowledge is directly used in software development.

Edit.: Thanks so much everyone for their great answers. Apparently boolean algebra is used by most people when comparing statements or refactoring code and knowing computer architecture helps people make better decisions about efficiency.

My symbolic algebra engine on C#

Hello, fellow csharpers!

I am a student and want to share with you my open-source project AngouriMath working with symbolic algebra. It's written on C# and allows to work with analytically-defined expressions: evaluation, simplification, derivating, solving equations, solving equation systems, and some more.

An example AM can solve:

(sin(x) + a)^3 + 3*(a + sin(x)) + c = 0

(but there're a lot of those that AM can't solve)

In addition to those algorithms, it has Numeric hierarchy (integer, rational, real, complex), true sets (with complex intervals), Tensors, and some more stuff.

I used many tricks and techniques there, yet still so far from Wolfram Alpha or even SymPy. One day I hope to make it more convenient & powerful than Math.Net symbolics.

Right now I'm working on optimization and decided to share the project with you. You can check the project on GitHub (under MIT => d

Is algebra taught in such a way that students are only following steps that they fundamentally don't understand?

I've heard so many people say that algebra is taught in a horrible way in school.

Richard Feynman called algebra education as "a series of steps by which you could get the answer if you didn't understand what you were trying to do."

There is this sense that people learning algebra in compulsory education are only learning algorithms to solve equations that they fundamentally don't understand. This seems to make intuitive sense because I can recall my calculus teacher being hopelessly unsure of herself without the formulas and "steps." If I'd ask her mildly complicated questions about the calculus (what it's actually doing, for example), she'd be honest with me and tell me that she doesn't know, but that if I follow these steps, I'll be able to get good marks on my tests and get into a good university.

Algebra is so fundamental, such that calculus is pretty much impossible if your algebra is bad. If algebra is learned in such a horrible way, what's the alternative? How can one teach

Any successful front end web developers here who literally don't even know any algebra like myself? Hi I only understand basic math but I want to leave fast food behind and become a front end dev.

Honestly I dropped out of high school and I'm now 31 and well I have literally forgotten all the math I ever learned, I'd say I'd got up to algebra 1 then dropped out. I still remember simple things like order of operations, very basic shit like that. Well is there anyone else in the same boat who successfully became a front end dev??? If I have to learn math again, that would easily be 200 hours of work and I already still have hundreds of hours of coding left to learn, I would just choose to go back to fast food if thats the case. But If I can really just learn to code and not worry about my atrocious math skills then I'm all in!

Yes, you will use discrete math and linear algebra

Something I hear all the time from freshman/incoming CS majors is 'Are we actually going to use discrete and linear algebra for cs? Those classes seem hard and useless', and I'd be lying if I said I wasn't one of them back then

I wanted to make this post for all of you who were like me and say yes, you will use them.

I was honestly shocked after seeing truth tables being rattled off in my systems programming class and was thankful I knew what was going on; it was also funny seeing the confusion of the students who definitely didn't pay attention/cheated their way through discrete.

Especially when you get into binary and bitwise operators in something like C, C++, or assembly, truth tables become very important in the same way matrices from linear alg become important for visual development and image processing.

So for all of you who are doubting their usefulness or are in either of these two classes now, pay attention and give it some time. The requirement of taking them wil

Do tagless algebra needs laws?

Hi all

I read the wonderful blog from JOHN A DE GOES regarding to tagless final. In the section 5.Fake Abstraction, he has mentioned:

> Unfortunately, these operations satisfy no algebraic lawsβ€”none > whatsoever! This means when we are writing polymorphic code, we have > no way to reason generically about putStrLn and getStrLn. > > For all we know, these operations could be launching threads, creating > or deleting files, running a large number of individual side-effects > in sequence, and so on.

He is correspond to the following tagless algebra:

trait Console[F[_]] {
  def putStrLn(line: String): F[Unit] 
  val getStrLn: F[String]
}

Does it mean, writting laws for tageless algebra is not necessary?

Tips for Calculus 2, Linear Algebra, Foundation of Algorithms from experience.

G'Day science jaffies. If you are going to do a Computer Science or Math major, you will most likely going to take at least two these subjects. And from my experience Calc2+LinAlg+FoA are 3 of the toughest subjects in Science Level 1 with high fail rates. These are the type of subjects that you wouldn't want to leave up for "I will catch up during the mid semester break" or SwotVac. Even if you're aiming for a mediocre grade, you will have to study every week and stay on track because once you fall behind you will regret that in the following weeks. I am going to put some tips about how you should study these subjects to achieve your goals.

  1. Calculus 2 (MAST10006): Personally I liked the subject. Probably Anthony Morphett was the reason I didn't give up and go home :v. You really don't need to study anything in advance for Calc2. The first 4-5 weeks is relatively easier and then the difficulty level will start to increase as you will be introduced to concepts like First Order ODE,

Linear Algebra Proofs

Until now I had never had trouble with math courses. But also until now (except geometry) none of my math courses dealt so largely with proofs.

Currently I am taking a Linear Algebra course and I am having tremendous difficulties. I am unable to solve most of the proving problems. Before that was the only problem, but now going into vector spaces I am becoming lost with all the terminology.

I was wondering I can get help with three things:

  1. Resources for becoming better with proving linear algebra problems. (I am assuming like everything in math becoming better at proofs comes with practice). By resources I mean like problem sets--with solutions--that I can practice.
  2. I have read a few past posts concerning Linear Algebra and it was described as one of the easiest courses they have taken. By difficulty coupled with this consensus has me worried. Is it normal to have trouble with Linear Algebra.

Anyone tried learning pre algebra to pre Calc before enrolling in wgu?

I'm working on a schedule to learn pre algebra, intermediate algebra, college algebra, trigonometry, and geometry before I enroll spring 2021. Is anyone doing similar? If so, how are you approaching it?

Over the last six months, I've researched memory methods, studying processes, srs systems, and finished a handful of book on mastering subjects of which the book Ultralearning was very relevant. In the book, the author attempted to complete a 4 year degree (Batchelor's) from MIT in 12 months. And he managed!

So I'm applying those "hacks" to streamline my learning. I'll share in another thread when I flesh it out for learning math.

So what was or will be your approach to picking up remedial math before enrolling?

How do you know which method to use when simplifying complex fractions? There's the writing as a single fraction method, and the multiplying by the lcd method. When do I use each of them?

What's the current state of Rust's Sparse Linear Algebra libraries?

Hello all,

I've been doing a lot of simulations recently, and I need to solve some large (2000 x 2000) symmetric and non-triangular sparse (~40000 non-zero entries) linear systems of equations where the matrices are changing in a tight loop. (The matrices are Jacobians of a highly non-linear function). The RHS vectors are dense. I currently store the RHS in a ndarray::Array1.

What's the best library to use for this?

I've been using sprs, but its performance was terrible in my benchmarking.

I understand nalgebra has sparse matrix support, but I was under the impression that nalgebra isn't meant for high dimensional systems such as mine.

EDIT: As many have pointed out these matrices aren't really large. I'll have larger ones in future iterations of this project, but should have been more careful with my phrasing.

Harder Class: Linear Algebra vs Managerial Accounting

Im in rbs w a double in cs, so linear algebra and managerial accounting are requirements.

I’m considering which course to take this summer, considering summer is condensed and offers p/nc.

Which one is harder and should I take this summer?

[Linear algebra]Find coefficients for which the system of linear equations are consistent.

Question.

Solution.

Is the reason why I cannot do: new r2 = 1/c r2 - r2 to get 0 d-d/c g-g/c because there is no invertible matrix I can multiply on the left that will that row operation?

How do we know that g-fc is non-zero? If g-fc is non-zero, then d-3c can take any value.

Thanks for your help.

[Linear Algebra] How Can I verify that something is a linear combination? Not sure how to set up this problem

How can I verify that this is a linear transformation, going from R3 -> R2?

T(X,Y,Z) = T[x+z, y]

I know in order for something to be a linear transformation, we have two properties which must be true, T(u +v) = T(u) + T(v), and T(cu) = cT(u). But, I am really not sure how to setup the problem in order to find this.

3 Topics of concern in linear algebra: Generally confusion about spaces. Why don't unsymmetric matrices form a subspace? Matrices characterized -- what they do.

The repetition of questions at the end are to focus where I need help. If you can answer any or all of these questions, please help and thank you so much. The 3 topics are separated by -'s and pair with the title.

Vector Space:

-----------------------------------------------------------------------------------------------------------------------------------------------------

A vector space is a collection of vectors closed under addition and multiplication. More specifically with an example: The collection of vectors with exactly two positive real valued components is not a vector space. The sum of any two vectors in that collection is again in the collection, but multiplying any vector by, say, βˆ’5, gives a vector that’s not in the collection. We say that this collection of positive vectors is closed under addition but not under multiplication.

This doesn't make sense to me.

I'd like to use a 2x2 matrix to understand this, with vectors A = (1, 1) and B = (1, 0) (a lower triangu

I will be taking a diffy/linear algebra course in Fall. I wanted to get ahead and start watching lectures but all the videos are separated as two completely different courses. Should I start both simultaneously or learn one then the other. If anyone has taken this combo course, I am curious if they bounce between topics.

Why do we bother with LU factorization in linear algebra?

If the goal is to solve Ax = b, and gauss-jordan elimination gives us A^-1 , then isn't getting x just as simple as multiplying b * A^-1 ? Why bother coming up with a L matrix and a U matrix and then doing forwards and backwards substitution?

I worked on a little algebra today

And while that may not seem like much, algebra has been my weak point since I was introduced to the concept and I will be a Jr this fall working on my engineering degree at university. I've already passed Calc III, but I know without algebra I won't be able to really thrive in any of my classes.

I've put it off so long now, it just feels good to put a little effort into it and make a little progress. Thanks for listening!

Are the concepts taught in basic linear algebra courses pretty standard? Will the Linear Algebra Done Right text book most likely be sufficient to prepare?

I will be doing linear algebra next year and I am trying to prepare because I will have a pretty heavy course load. I've went through calc 1 and most of calc 2 and the concepts there are fine but now I would like to know the best way to prepare for linear algebra. I have the textbook "Linear Algebra Done Right" in PDF form and I'm wondering if anyone would recommend a different text book and if they know if this textbook covers enough of the material that is likely to be taught in my linear algebra class. I will be completing the course in 3 weeks as opposed to 11 so for this reason I will definitely need to be as prepared as possible.

Should I keep taking algebra 2 this summer?

I am a rising sophomore, and a couple weeks ago I started taking algebra 2 online through Apex Learning. For context I took Algebra 1 in 8th grade and Geometry freshman year. I thought it would be a good idea to take this to catch up to some of my peers who took algebra 1 in 7th grade.

So far the course has been mostly Algebra 1 review, but I know it won’t be review forever. I am doing probably at least 3 hours of work a day so I can finish the first semester by July 10th, and the second one by around August 10th. I am doing multiple quizzes every day, along with tests once or twice a week. I am also doing lessons every day.

I am starting to regret my decision of signing up for it. I feel like the amount of work I am doing daily is really taking a toll on me, and I am questioning if it’s worth it to stay in and finish the class. I feel like I would learn the concepts better in a classroom setting over the school year rather than me trying to learn it all almost on my own in 8 weeks

The Necessity of Linear Algebra in Computer Science?

[edit] I've found someone! Thanks for all your suggestions <3

Hi everyone!

I am currently going into my second year in computer science, as well as currently taking a course in linear algebra. We have been assigned a project which requires us to interview people in the workforce who specifically uses concepts of linear algebra in their work. I have reached out to some people in a handful of other fields but had found that the use of linear algebra only applies to some very specific projects/jobs.

I am still very new to this field, so I want to explore the concept of linear algebra in relation to computer science. I was wondering if anyone would be available to help me answer some questions (small interview) about their background & jobs in relation to linear algebra?

Thank you!

Here's how many hours(without breaks) it took me to finish algebra 1 and geometry.

Do you like statistics, data and stuff? I do :) I wasn't super terrible at math in middle and high-school, but to get B was an achievement. I still suck at math now. Never liked it. Then barely managed to enroll to university and get 100% scholarship. It wasn't hard, it's no big deal here in Kazakhstan(not like in the US). Every my classmate got it. I don't know a proper name of my major in English but it's something about industrial automation. I'm russian btw. Also started learning English 2 years ago. And now I'm halfway through the graduation, barely keeping up with my classmates. I'm in bottom 1/3. Now I can learn stuff in English and it's much more fun and much more content available than in my mother tongue. Now I decided to kill my fear of math and improve my math foundation. That's why I chose Khan Academy. Then I will use openstax books. So, as a result, I figured out that I learned math on Khan Academy more than in all 11 years of school combined.
