## Derivative of Logarithm

When the logarithmic function is given by:

f(x) = log_{b}(x)The derivative of the logarithmic function is given by:

f '(x) = 1 / (xln(b) )x is the function argument.

b is the logarithm base.

ln b is the natural logarithm of b.

For example when:

f(x) = log_{2}(x)

f '(x) = 1 / (xln(2) )
