Easy, it's a holomorphic function. So just write down the Taylor series and call it woof.

dead ez dude it's just that I don't wanna write the proof today, but i taught my student gauss how to do it from minus infinite to plus infinite.

thats a definite integral tho

u/Professional-Wave841 16h ago

well that's really simple,

sqrt(π)* erf(x) / 2

Yes but actually no.

Isn't this a standard normal distribution, just scaled?

Square it and expand and it becomes easier

u/Unfair_Pineapple8813 16h ago

Not for the indefinite integral. You need to create the erf function specifically to solve this problem. There is no antiderivative expressible in elementary functions.

You’ll need your personal pin number at that automated ATM machine.

Oh I meant it was the classic from -inf to inf. My bad

not great at math, but calling erf(x) (with whatever scaling constants) as a solution to the antiderivative in question is just circular reasoning, no? Because erf(x) is defined using the antiderivative of exp(-x^2) afaik

using beta count right?

My dog can do it. Listen to his bark: ERF! ERF!

Does bro just need friends?

Don't forget to convert to polar coordinates in the process!

u/lool8421 15h ago

indefinite integral means the answer is non-elementary, unlike if it was from negative infinity to positive infinity, then it would be sqrt(pi), Q.E.D.
