Hi Just wanted to see if anyone could tel me if i have found the derivative correctly F(x) = 15e^(-x)ln(x+1) F'(x) = -e^(-x)((15x+15)ln(x+1)-15) / (x+1) Is there any programs on the internet that you can download that calculate this out?

Somethings is wrong $\displaystyle \frac{d(15e^{-x}ln(1+x))}{dx} $ $\displaystyle = -15e^{-x} ln(1+x) + \frac{15 e^{-x}}{1+x} $ Once you will practise it you won't really need that
