You might remember me from my previous summaries of intro differential equations and multivariable calculus. Since releasing those, many have asked me for a summary of single variable calculus and I'm happy to say it's completed.
Just like the previous summaries, it contains explanations of every topic, over 100 examples, and 3 worked tests (this time AP exam free response sections).
Please let me know what you think or if you find anything that needs fixing. If you're savvy with git, you can also open an issue or pull request here for any of the summaries. I'm always looking for better explanations and especially better visuals.
Hopefully this will help a few people come exam time this upcoming semester or just be a good refresher.

Common knowledge? Recent update?
*EDIT* Thanks for the comments.
TL;DR: This is deprecated and bad practice
I'm using Jupyter But it doesnt have that assist feature?
Often I have to keep scrolling up to see what arguments the function takes, especially for some really large functions that take many inputs.
Is there an IDE that has an assist feature, where as you're typing a function, theres a pop up box that tells you what arguments it takes? Kind of like the way excel does?
FYI the Facebook ad game has changed A LOT over the last 3 years.
3 years ago, you wanted to run traffic campaigns to get as many people to your site as cheaply as possible. Cheap clicks at a high enough conversion rate = eCommerce success.
But that has changed. Now, instead of bidding on traffic and trying to get cheap clicks, you want to optimize for purchases because Facebook is really good at getting you what you ask it to give you. Even if you pay more per click (trust me, you will), you'll still make more money (you have to trust me on this one too). The goal now is MORE SALES not CHEAP CLICKS even if that means you PAY MORE PER CLICK.
Ok, so that's one important change that we need to be aware of. What else should we be paying attention to?
Something else that has changed is audience hacking. 3 years ago, you wanted to spend your time to test to find the perfect audiences. By hacking and testing, you eventually would find audiences that would perform better than others. This took time and money to test, but it was worth it.
But that's not true anymore. Facebook has gotten A LOT smarter since then. That means you no longer need to "audience hack." Instead, you want to go broad, optimize for purchases, and then let Facebook do its thing to find your customers.
This doesn't mean that Facebook ads are now on auto-pilot. What it does mean is that you don't want to spend your time trying to find the perfect audience. This will be a huge waste of time in 2020/2021 because you're spending your time trying to find the perfect audience when you should be spending your time on something else...
So what should you be doing instead?
The #1 thing you should be focusing on in 2021 is AD CREATIVE. This is the single most important lever you can pull in 2021 that will have the biggest impact on your ad success.
You could spend months audience hacking and maybe improve results 10%. OR you could invest in awesome photography and video assets and then have a talented team design Facebook-optimized, conversion-focused ads. These ads can have a 2X impact on your sales.
The main thing to take away is that WEAK ADS lead to WEAK RESULTS while STRONG ADS will have the BIGGEST IMPACT on your sales.
Based on that, most of the time, you're better off simplifying thigs and running 3 top of the funnel prospecting ad sets optimized for purchases. (1) Lookalike stack of 2-5 top lookalike audiences (5% purchase, 5% add to cart, etc.) (2) Interest stack (t... keep reading on reddit ➡
Lasso uses L1 penalty while Ridge uses L2. Lasso can force some coefficients to be 0, while Ridge can't
I've seen the plot of the ellipses with the x,y coefficients and Lasso represented with a square and Ridge with the circle, but I don't understand why Lasso can force some coefficients to be 0 and Ridge can't
Is it not uncommon for interviewers to ask MLE/DS candidates as to why Lasso can force some coefficients to be 0 and Ridge can't? If so, what is a good explanation for this?
My first two pregnancies I did not have this. Will there be more nurses? I know my chances of c section are higher (first two were vaginal deliveries). What else can I expect? Of course I've never had a pandemic era delivery either, so anxiety is very high!!!
HSBC just shattered the floor for insured high-ratio mortgages at 0.99% for a five year variable mortgage today. Is this the first sign of housing'mageddon?
Another beta, or should I say, release candidate? 😁 Hopefully I can release this to the general public soon if there are no more issues introduced by the recent betas.
Sign up for the beta here.
If you don't want to wait for the Google Play update, get it right away here.
You can also get the updated app factory here.
Pick Input Dialog (pick files, folders, time, apps, etc as a Tasker action): https://youtu.be/jjNlEYqN-Aw
Multiple Variable Set: https://youtu.be/__Sbx-SO8H8
Set Launcher (and Go Home to specific launcher): https://youtu.be/UiGrxHBUBh4
You know all those types of data that you can pick in the Project/Profile/Task variables? You now have that in the form of a Tasker action so you can pick these inside your tasks! 😊
*Sigh* Another AutoTools feature is now mostly in Tasker 😋
These are the currently supported types but I can always add more!
And another AutoTools feature comes to Tasker 😏
You can now set multiple variable values in the same action. You can set custom separators for both variable names and values.
Can be a great time saver!
The ADB Wifi action now has a helper to set your launcher so you can change that dinamically!
Furthermore the Go Home action now also allows you to set a specific app where you want to go home to, so even if you don't have ADB Wifi you can always launch a specific launcher from Tasker at any time!
Lately a lot of spammers are using compromised accounts, usually from people who used the same password in another site whose passwords were leaked. The filter for new accounts that most medium or large subs have doesn't work well in this case because those accounts often have age and karma to pass the test. But due to reddit's diversity it's very unlikely that they have any karma in the sub the spammer is targeting. So a variable in AutoMod with the value of the karma of the user in the specific subredit would allow the mods to set up a simple filter to combat this kind of spam.
Such filter would also help in brigading cases because in most cases the users brigading never posted in the sub before, even though they often have age and karma to pass the new accounts filters. And it would reduce the problem of spammers using the subs that encourage giving karma for no reason.
I know this variable is stored in the system because you can see it in your profile in old reddit and the system blocks a post if you try to post twice in 10 minutes (or 15 I am not sure) in a sub where you have low karma (I think it's under 100), no matter how high you general karma is. So it shouldn't be that hard to pass that variable to AutoMod.
I know that some people will be afraid some mods will, even by accident, block all new users using this to remove and not filter. Personally I think they should be allowed, but if you want to avoid that make it a toggle in the subreddit settings: "Filter posts from users with less than X karma in the sub?". No option to remove and you could even make a setting that says that such filtered posts will be auto-approved after X hours if a mod doesn't confirm the removal. It would even be more user friendly considering most mods don't know how to work with AutoMod,
I'm following this tutor
I really cannot understand what's a object, class, methods, and instance variables
By googling, I get even more confused, because they tend to use specific terminology that I cannot understand.. can someone explain it to me in kids words what they are?

I Have the Array Variable (a,b,c,d)
%var1 = a,b
%var2 = c
%var3 = d
How to change separator ?
%var = (a,b,c,d) it Contains only 3 var - i get this Value from database so i have Array variable..
Case 1 : %var1= a,b | %var2=c | %var3=d Case 2 : %var1= a | %var2=b,c | %var3=d Case 3 : %var1= a | %var2=b | %var3=c,d
I dont know which Case is true... there is only way to know..flash %var1, %var2,var3..
There is no possibility to check flash all the time..
How to Change separator
The concept of Voyager's nacelles angling upward 45˚ prior to entering warp has always fascinated me. The basic idea here, for those who may have forgotten, is that the variation in geometry helps reduce damage to the spacetime continuum. More specifically, the theory (ostensibly proven during the events of TNG: "Force of Nature") is that travel at warp speeds induces damage to subspace (Picard compares it to running up and down a carpet; after a while the carpet gets worn out), ultimately disallowing the generation of a stable warp field.
We can take it one step further from Voyager. The Jellyfish also employed a rapidly rotating aft section - for sake of argument I will presume that this is akin to Voyager's movable nacelles, in that the attempt from the Vulcan Science Academy was to lessen the burden of warp drive on subspace.
What I'd like to do is provide a somewhat mathematical framework to the "stresses" that subspace experiences due to propulsive warp bubbles.
Geordi has mentioned before (TNG: "Schisms") that the dimensionality of subspace may be thought of as cells of a honeycomb. This got me to thinking about actual cells, and how a correlate may be made between them and space.
Let's assume, as a first approximation, that subspace cells have, for lack of a better term, a Young's modulus. If we assume Hertzian mechanics, single cell compression can be modeled at low deformation - textbooks usually take it to be at levels under 40%. I cannot imagine that warp fields deform subspace cells to an extent greater than 40%, though I might be wrong. Again, this is just an assumption.
At low deformation, during the initial compression, subspace cells may be treated as a balloon filled with an incompressible liquid (is the nature of space, sub- or not, compressible?). Under Hertzian contact, the force should follow:
F = F^(SSE) + F^(WF) = 2π(E^(m) /1-v^(2m) )hR^(0) ε^(3) + π(√2E^(c) /3(1-v^(2c) )R^(02) ε^(3/2)
where SSE is the subspace envelope, WF is the warp field, R^(0) is the radius of uncompressed subspace cell, h is the subspace envelope thickness, E^(m) and v^(m) represent the Young’s modulus and Poisson ratio of the membrane, respectively, and E^(c) and v^(c) are the Young's modulus and Poisson ratio of the warp field, respectively. Finally, ε is the relative deformation of the subspace cell.
If this follows logically, the contribution of the warp field should follow ε^(3/2... keep reading on reddit ➡
