**MathMate**, Wednesday, December 14, 2011 at 11:33pmWhen the exponential function is multiplied by a factor which is the derivative of the exponent:

d/dx x^3 = 2x^2, then

the integral is simply the exponential function, with some constants to be adjusted.

If you are not sure, try differentiating

e^(x^3) and you'll get the picture.

It will save you a lot of time, let say if you try to integrate by parts:

x^99 * e^(x^100) !
