Thatβs what you get for inventing calculus

The importance of the fundamental theorem of calculus (for my career)

Itβs funny how important a little piece of mathematics that we teach kids in high school can be. The fundamental theorem of calculus demonstrates that if you integrate a derivative, then you get the original function back.

This simple idea tied together with a little Hilbert space and operator theory has become the keystone of my work over the past three or four years. My group and I have published paper after paper making aspects of data science and nonlinear dynamical systems better using the product of these three concepts, which we call occupation kernels.

We have brought in over a million dollars in grant money for our work, all on the back of the FTC and Reproducing Kernel Hilbert Spaces. One YIP, an NSF grant, and an AFOSR grant.

It really blows my mind sometimes. Having a solid understanding of fundamentals can really open up opportunities that others miss. I am just grateful that we had the wherewithal to put these ideas together.

What surprisingly simple idea has had a major impact on your work? Or have you been surprised to find a simple theorem leveraged to resolve a big problem in some circumstance?

EDIT: So around 300 upvotes is apparently when imposter syndrome kicks in lol. I thought this post would get a little attention, and we'd have a nice conversation about system identification. I am overwhelmed with the positive reception here. You guys are great :)

People who say stuff like Trigonometry and Calculus will never help you in the real word are complete idiots

This goes for all math really. Just because your job doesn't require math doesn't mean others don't. Just think of all the things made by engineers. Cars, planes, washing machines, phones and so many more. These were all made by using math. If math were never here then we would be living in a completely different world.

I Aced My Calculus 2 Final

After dropping out of Calculus 1 two times, taking Precalculus 3 times, dropping out of college and coming back after 7 years, I have finally completed my math requirements needed to transfer over to a 4 year university. My 20s have been an emotional roller coaster. From mental breakdowns to a failed marriage, I feel like my life's on the right track now.

I'm proud of that A, I worked hard for it dammit.

Where should I go after Calculus?

Hi. I'm 60 years old, and started relearning math two years ago, starting from arithmetic and going up to Calculus. I used OpenStax at first, and after finishing their math library I moved on to Tom M. Apostol's *Calculus* with the help of my nephew. What topics should I cover next, and what are the best textbooks for them? I would prefer something similar in rigor to Apostol's series if possible.

Havent taken a math class in 10 years, need college algebra, calculus, and discrete math, where should i start?

Hey all, just decided to go back to school a few months ago and have completed all my other gen ed courses. Been waiting to do kath so i could do them all in rapid succession.

Havent taken math since high school algebra about 10 years ago. I have always liked math and been quick to pick it up just dont remember much from back then.

My goal is to test out of college algebra (CLEP) by the end of june then take calculus and discrete math through study.com

I defintiely need a refresher on the algebra basics and am planning on using khan academy.

I am also working through the logic and fundamentals of mathematics on brilliant.org and will probably continue through some of the algebra courses on there as well.

Would you reccomend doing anything else? Thanks in advance.

Calculus got me fucked up

In high school calculus this man was tryna cheat with a notecard up his sleeve so i snatched it and ate it and said no one is gonna believe you and he tried to tell on me and no one believed him lmfao

This calculus problem really makes me smile because of how beautiful it is. Hope it makes you smile as well.

Calculus 3 is hard

This is the hardest math class Iβve taken so far in college. Cal 2 was much easier than this. I didnβt quite understand sequences and series in cal 2 but after much practice, it became easy to get. I got an A in both cal 1 and cal 2, but cal 3 is different.

It was easy at first until βMultiple integration and vector calculusβ. I donβt understand geometry and it has been my weak point in math since highschool. I donβt get the 3D surfaces and how to find the endpoints to the integral. I also donβt know how to interpret the question with a diagram. Finals are next week and Iβm exhausted. I can get an A in the class based on my homework grades, previous exam grades and how well I do on the final, but this is the toughest math class for me.

Logical question. Calculus!

Fun fact, the damage from The Ultimate Nightmare of Wizards of the Coast Customer Service card can be optimized using calculus

Many know about the card The Ultimate Nightmare of Wizards of the Coast Customer Service, hereby abbreviated as TUNWCCS, from the parody set Unglued. The effect is to pay X+Y mana plus two red mana to deal X damage to Y targets. (For all intents and purposes, we'll assume Z is part of Y, as players are just additional targets.)

Those who have taken calculus may remember those optimization problems where we find the maximum of a function with respect to some constraint. For example, optimizing the area enclosed by a fence with a certain amount of money to buy fencing. Well it turns out that maximizing the total amount of damage from TUNWCCS is basically the same problem.

In particular, the total amount of damage dealt D is given by D = Xβ Y. If we have M mana total to spend, including the two red mana, then we are subjected to the constraint that X+Y+2 = M. Solving for Y and plugging into our original equation, we get that D = Xβ (M-X-2). Taking the derivative and setting it equal to zero, we get that the optimal choice of X and Y are X = Y = (M-2)/2, and the maximum total amount of damage that TUNWCCS can deal is D = (M-2)^(2)/4. In particular, the number of targets chosen and the amount of damage to deal to each target should be equal to maximize the total damage.

And they say pure math has no real world applications.

edit: Some of you have mentioned that the modern versions of this card are Comet Storm or Strength of Tajuru. These cards are slightly different since the first instance of damage/first counter is free.

Let D be the total damage or total number of +1/+1 counters. Then let Y be the number of times the multikicker cost is paid. Then in this case we have D = Xβ (Y+1), and again we have the constraint that X+Y+2=M. Again solving for Y and plugging into our original equation, we have D = Xβ (M-X-1). Again taking the derivative and setting it equal to zero we get X=(M-1)/2, then solving for Y we get Y=(M-3)/2, and the maximum damage/number of +1/+1 counters is D=(M-1)^(2)/4.

For example, if M=7, we should have X=3, and Y=2. In other words, to maximize D, we shou

My Calculus 2 door for finals (order zig-zags starting from top right. Page # on bottom right of each paper) reddit.com/gallery/n84tap

(12th grade, AP Calculus AB, Exponential Decay) I have tried several different methods and gotten several different answers (including the one in the picture). What on earth am I doing wrong?

If someone asked you what calculus is, how would you respond?

I'm an undergrad majoring in Computer Science, but when one of my parents asked me what calculus even is, the best answer I could give was the study of derivatives and integrals. For people that don't have a math background, this answer doesn't really help much so I was wondering if anyone has a better explanation.

Economics expressed in Mathematical language? Set theory, calculus, algebra, statistics, Operations Research... what tools do I need to express economics rigorously?

I have a STEM background, math-heavy. I now have to study Economics very quickly, both Micro and Macro. It's written in plan language, and, at first blush, the assumptions of Neoclassical theory seem weird - people don't have explicit and consistent utility functions that can map any basket of commodities to a single numerical Real value, or even ones that can consistently organize the sets of possible baskets by preference or indifference.

However, these formulations started to make sense to me once I tried to phrase them as mathematical statements - I'm getting the impression that they're an effort to take a very complicated and messy reality and express it into tidy, mathematically rigorous models. You don't really answer the question you set out to, but you answer one about something that's somehow close to your target while being much easier to measure and model and operate with.. It's the resource-allocation equivalent of physics' infamous "perfect rigid sphere through a frictionless void on a perfectly straight inclined plane with infinite friction coefficient and no slip or rolling resistance being released at time t=o with velocity v=0" as something that is utterly deranged and surreal at first glance, but is a useful first approximation on the long road to "how should I build the brakes on this car so it can go down the steepest hills with roads on them at a fluid yet safe traffic speed" or "how do I design the rails and wheels on these drawers so that they slide down into place when released and slow down *smoothly* at the end so that they close *just so*".

Sorry for the detour. TLDR, what I mean to ask is: what are good textbooks on "economics for STEM-trained dummies" or "economics in math-speak" or "good luck writing any of this digitally without generous helpings of AMS-LaTeX"?

Why learn Calculus?

Is there a legit really really good reason to learn it? If there is, what is it? Thanks!

edit: thanks for the comments. I should learn calculus then.

how important is it to be able to do physics/calculus fast?

I'm starting to learn it, and while I can do pretty well, I take a way longer time than I should. it's not the concepts that confuse me, I'm just slow. I'm honestly thinking about asking for accommodations for it during tests, but would that have an impact on my future? Like in what field would it be important to be able to do these problems fast?

Best textbooks for self-learning Calculus?

I would like to have a textbook with good practice problems and also teaches you some things about calculus. Can anyone help me?

Just finished my Calculus class. Iβm feeling fine.

history question : how did calculus go from making predictions about physical objects to more abstract things like economics?

Things like derivatives were originally used to describe physical objects, and now they are widely used in economics. how did this happen? I'm not sure if theres a clear answer but i'm wondering

How should someone who has been out of school for a decade go about learning enough algebra to begin studying calculus?

In other words: assuming I already know basic arithmetic, where should I start the "journey" to learning calculus? What is absolutely vital, and what can be bypassed? About how long would it take? (Obviously, it's different for everyone; but are we talking weeks, months or years?)

What even is "Prep" and can Iceman learn calculus in 6 months?

Batman vs. a Silverback Gorilla with guns conveniently coming from all of its everywhere BUT THE GORILLA GETS A MONTH OF PREP

**Prep**.....that magical word that gets used so much for so many things and yet is defined almost as frequently as it is taken into consideration, and that is to say....basically never. Prep time is most infamously used in threads revolving around a few characters (DOOM) and most people generally understand super geniuses will do super genius stuff when given time to prepare but I have a few problems with "prep" and the way we use it and for this example I will be using Iceman.

**What is Prep?**

Prep is rarely defined in a thread more than simply "X amount of time to prep" but not what the person is allowed to do with that time. There are a lot of very important things to know for what "prep" time means.

- Where can the person go when they have prep? Are they in their home world or their opponents world? Iceman in Marvel has more resources and friends than he would in the Hidden Leaf Village.
- What information do they get access to? There aren't any books in the Baxter Building or the X-Mansion about Naruto so are they provided with some kind of dossier on their opponent or do they need to spend time doing recon and learning about their opponent.
- Can they alter the field of battle? If Iceman knows he is going to fight someone in the middle of the desert but has months to prepare, could he make a giant above ground pool to supply him with extra water and moisture?

There are so many undefined terms of what Prep is that it is hard to factor in what a person could even do with the time. A character like Iceman who is not a super genius who could spend time building a death laser may not have much to do with prep time.

**What do People do with Prep?**

This is why I chose Iceman over Doom, and I know, that's a bummer for everyone, but this is really what got me thinking because for characters who aren't geniuses what *can they do with prep time!?* With genius characters most people will basically fill in whatever answer is needed to win because they assume with time to prepare geniuses will figure it out. However for characters who aren't geniuses, it is harder to think what would they do, given the time to prepare.

For example, if you give Iceman 6 months to prepare to pass a math test, would he learn calculus in time to ace it?

Now we go back to the above section for a moment to say, well, what resources does he have? Beas
