Natural Log Derivative: f(x) = 3*ln(4 + 5x^2)
Description: How to take the derivative of the natural log function with a function in the ln function. This is a common problem in calculus that students struggle with. The derivative of ln(x) is not 1/x it is the derivative of x divided by x which happens to be 1/x but this fails for all other cases that are polynomials of degree higher than 1.
