Math - Integrals and Differential Equations

Khanacademy videos?

There's another thing that triggers me hard.

Symbolab results are different from the results of my teacher.
Why the fuck humans landed on the fucking moon, but there's not even a single bright mind that codes a fucking app that solves all this integral shitstorm?
Seriously...

Moon landing is pretty trivial when split in small enough subproblems and many people work on project. Integration have many special cases and honestly no gain of programming calc for every special case.
Sure offer 1 million for such app and there will be app for it.

If you are not total brainlet just study some more.

>tfw I failed "Differential Equations" 5 times in Uni

it was the only class i fail. The only one, it made Uni 1 year longer because I couldnt learn itn it was impossible, no matter how many classes I took I always forget about them 1 week later. I always forgot it for the next semester, It didint fit in my head at all.

I was so close to take another career but I took this class witha professor that was accused of sexual harassment and he help us so much because he want us to defend him on a court or something

Dude, you just gave me a great idea.

Right now unfortunally I've got to study this shit, I don't want to fail the second exam.
But I will open a kickstart campaign to get 1 million to pay a team to code that app and make it available for 49,90$/month.
It will be possible to use the app on the phone and on the nspire cx cas calculator.

And you know what? I fucking bet that I will be able to get the million to do it, because there's millions of students in the same boat.
You can screencap this.

What do you not understand exactly?

Just fucking bash your head against it until you get it. Or until you get correct results. There is no other way.

Are you going to study today? Can you study today?

Man never landed on the moon, lunatic

>49,90$/month
Lmao nobody's gonna buy that trash for this price.
Make it a one-time $30 payment and I'll think about it but otherwise? Naaah.

Sorry man, best I can do is 15$.

But in all seriousness, I would fucking dump 1000$ on it if I could use in on my calculator, because that would mean a 100% sure exam approval.

Definite integrals are just evaluated at the endpoints. An integral is just an area, so unless they throw discontinuities at you (i.e. the integral isn't continuous at all points) just subtract the evaluated value of your indefinite integral at end point from the starting point. A derivative is the opposite of an integral and is taking an instantaneous value (it's a tangent to a point on the function curve you're looking at).

Symbolab has not once failed me from calc 1 to calc 3 and into DE (had to switch to wolfram alpha for DE), so i don't know why you have a moron professor who can't solve math problems correctly.

change majors kiddo

nice
thanks man

there's nothing to understand, you just memorize the derivatives of common functions and simplify an expression using changes of variables or integration by parts until you find something you already know.
start with the simple problems and you'll figure out the common tricks that make you able to solve harder ones
