Question
3.3.1. Derivatives of Logarithmic Functions
The derivative of the logarithmic function is determined by the
following theorem.
Theorem 3.3 Chain Rule of the Derivative of Logarithmic Function
Let a be a positive real number (a # 1) and let u be a differentiable
function of x and u(x) > 0, then
1 du
и dx
du
(loga u)
(In u)

The second formula is a special case of the first formula since the
natural logarithm In u = log, u.
In the first formula we can set
a = e thus In a = In e = 1.
