# How to find the maxima/minima of a function using a software?

I want to find the maxima/minima of a function in an interval. Is there any software or online tool available for this?

The particualr function I want to maximize is, $$f(x) = x(1 - \sqrt{2e} \cdot x^{\frac{1}{2}} e^{-x}), 0 < x< \frac{1}{2}.$$

Wolfram|Alpha should be able to handle that –  dirty derwin Jan 6 '13 at 7:07
