### LeonhardEuler

That can not be done. There is no elementary function whose derivative is $e^{x^2}$. There is a special function, erf(z) defined by:
$$erf(z)=\frac{2}{\sqrt{\pi}} \int_{0}^{z} e^{t^2}dt$$
Is that the full question, or was it a definite integral? There are special tricks to finding certain definite integrals of this function.

Just to add: 'Integration' not 'intergration'.
