open your calculus book and start reading it. if you get to something you don't understand, read it over and over (and the parts before it too) until it makes sense.
also definitely don't try learning it from a rigorous analysis book. just use a high school/college freshman book that has colored pictures instead of proofs.
this sounds condescending but im just trying to help

I don't understand how you can't spend a couple days reading a book. Just find a topic, and read it over and over again. Why is that so fucking hard? Why can't you just fucking teach yourself?

If you're having trouble with calculus, chances are you don't know the algebra well enough. Maybe your middle school / high school sucked, maybe you were just lazy.

Whatever the case, make sure you know some basic trig / algebra / functions beforehand. See the introduction of any generic calculus textbook (like Stewart)-- they usually have 'diagnostic tests' before the first chapter. If you don't know this stuff well enough, you're going to get questions wrong and know know why.

this. I struggled with calculus for a while, eventually I realized it was because my algebra foundation was weak. wasn't until I got to diff eq that I filled in the missing pieces with pre-calc problem sets. never had problems with the conceptually applying calculus, just the algebraic details

You're not dumb, there's a complete correlation between aptitude at math and how long one is willing to work at something. That's why Asians are better at math, because they work longer.

The absolute easiest way to understand calculus is to, no joke, make a khan academy account and do the AP Calculus AB stuff. Its the simplest, most focused way Im aware of to learn calculus. Im sure you will miss some autistic component but you will gain at the very very least an awareness of what calculus is. Autists in this thread would shit on it but it would blow Newtons fucking mind so wtf do they know.

Gotta say most teaching just makes it harder. Calculus is actually in some ways similar to how if you didn't know an answer you could figure it out by brute force. It may be formalized now but it's like if someone said I figured out how to find the number of bricks in a house and then just stood there and counted each one. Idc if that doesn't help fuck you ahahaha

>redpill me on calculus
The behavior of general functions is complicated, but the one of linear functions is simple. So if you want to investigate the behavior of a function f at a point x, you make the problem easier by looking for the best linear approximation of f at x. The best linear approximation is exactly the derivative. It gives you a lot of information about how the function behaves around the point, even though the information is local.
The connection between local and global is then given by the fundamental theorem of calculus - it says that you can stitch together the local information of the derivatives to reconstruct the actual function and exactly how to do that.

Quoted By:

In the case of real functions the viewpoint of the derivative as the best linear approximation can be overlooked just because the definition is so simple, but you can't avoid this viewpoint when you try to define derivatives in functions f: R^n -> R for n higher than 1. Technically speaking, in the case R->R the value of the derivative is the slope of the best linear approximation, not the linear map itself, but it could have just as well been defined as a linear map L:R->R such that
lim of (f(x+h)-f(x) - L(h))/h = 0
h->0
I'll leave it as an exercise to see that these two definitions are actually equivalent :)
The fundamental theorem of calculus is also remarkable in the following sense. When I was a child, I tried to think about what exactly the speed means. Sure you can take the ratio of distance with time between two distinct times, but that would be the average speed. What is the speed right now? Turns out the intuitive notion as taking the limit of the average speed as the future time point tends to the present time works out well. And then you might wonder, if you know the average time in the time interval, you know how far you traveled (by multiplying by the time), could you do a similar thing with instantaneous speeds? There are infinitely many speeds, because there are infinitely many time points at which you could have measured the speed, so what do you add and multiply? And what the FTC says is exactly that the intuitive thing to do: to consider instantaneous speeds as average speeds for small time intervals and calculating the distance in that way, while making the intervals smaller and smaller, the limit is remarkably the actual distance that you traveled! That seals the deal: derivatives are the right thing to look at and calculus is based!
