Differentiation of Exponential Functions
Formulas and examples of the derivatives of exponential functions, in calculus, are presented. Several examples, with detailed solutions, involving products, sums and quotients of exponential functions are examined.
The derivative of f(x) = b^{ x} is given by
Note: if f(x) = e^{ x} , then f '(x) = e^{ x} Example 1: Find the derivative of f(x) = 2^{ x} Solution to Example 1:
Example 2: Find the derivative of f(x) = 3^{ x} + 3x^{ 2} Solution to Example 2:
Example 3: Find the derivative of f(x) = e^{ x} / ( 1 + x ) Solution to Example 3:
