L20 - 7 Logarithmic Diﬀerentiation 1. Take natural logarithms of both sides of an equation y = f(x)andueheawsfoahmsoi . 2. Diﬀerentiate implicitly with respect to x. 3. Solve fordy . dx We can use the processL ofgarithmic Diﬀerentiation to ﬁnd the derivative of a complicated expression which does not contain logarithms initially: √ ▯ 2x − 3 ex. Find f (x)i f(x)= e secx .
