In Summary

Derivatives of exponential functions is a fundamental concept in calculus. The most common type of exponential in this section is f(x)=ex, but we also look at bases other than e like for example f(x)=2x.

There derivative of ex is ex
ddxex=ex

The derivative of an exponential with a based other than e is
ddxbx=bxln(b)

For example,
ddx2x=2xln(2)
