Derivatives of Logarithmic Functions. The differentiation of log is only under the base e e e but we can differentiate under other bases too. We begin by using the following log rule to simplify our question.
If a e we obtain the natural logarithm the derivative of which is expressed by the formula lnx 1 x.
Ln b is the natural logarithm of b. We begin by using the following log rule to simplify our question. A logarithm is the opposite of a powerIn other words if we take a logarithm of a number we undo an exponentiation. Rewrite log 2 40 log 2 5 as a single term using the quotient rule formula.
