RE: Why is this?

Is it purely coincidental that the max - The derivative of y = x * e^(-x^2) is y' = e^(-x^2) * (1 - 2 * x^2) - To find the extrema of y you must solve y' = 0. - The exponential term is never 0 and the polynomial term 1 - 2 * x^2 is 0 for x = Sqrt(2) / 2, which is where y has a maximum. - There's no relationship whatsoever to the sine function, just numerical coincidence with the numerical value of sin(45 deg), that's all.
