Question

What is the integral of e^(-x^2)?

Answer 1

e^(-x^2)/-2x????

Not to be mean that is way off.

This intergal cannot be solved analytically.  You need to find the power serious representation of the function and intergrate the resulting plolynomial.  The number of terms you take it out too depends on the desired precision of your result.

Or you could do it numerically.

I think you can also use a Fourier Series if your clever enough, I think we had to use Fourier to solve a similar intergal in one of my classes... that was 4 years ago....

Answer 2

e^(-x^2)/-2x
