Derivative of Logarithm
When the logarithmic function is given by:
<span>f </span>(x) = logb(x)
The derivative of the logarithmic function is given by:
<span>f ' </span>(x) = 1 / (<span> x</span> ln(b) )
x is the function argument.
b is the logarithm base.
ln b is the natural logarithm of b.
For example when:
<span>f </span>(x) = log2(x)
<span>f ' </span>(x) = 1 / (<span> x</span> ln(2) )
