Hello, ive tried everything i know how to do and i cant do this(!):
$\displaystyle \int{e^{x^2}}dx$
Its not very clear but thats e to the power of x squared.
Thanks!
It cannot be done using a finite number of elementary functions (this can be proved, by the way). An answer can be found using the Error Function erf(x): Error function - Wikipedia, the free encyclopedia
yup.. this is a very interesting question.. it cannot be solved directly due the the reason provided above.. however, the ans can be approximate by converting e^(x^2) to some polynomial using lagrange interpolation or using taylor series. It should be able to get some very close approximation
