Find the derivatives of various functions using different methods and rules in calculus. Several Examples with detailed solutions are presented. More exercises with answers are at the end of this page.

** Example 1:** Find the derivative of function f given by

__Solution to Example 1:__Function f is the product of two functions: U = x

^{ 2}- 5 and V = x

^{ 3}- 2 x + 3; hence

** Example 2:** Calculate the first derivative of function f given by

__Solution to Example 2:__This function may be considered as the product of function U = √x + 2x and V = 4x

^{2}- 1, hence the use of the product rule

** Example 3:** Calculate the first derivative of function f given by

__Solution to Example 3:__

The given function may be considered as the ratio of two functions: U = x^{2} + 1 and V = 5x - 3 and use the quotient rule to differentiate f is used as follows

** Example 4:** Calculate the first derivative of function f given by

__Solution to Example 4:__Function f is the quotient of two functions hence the use of the quotient rule

** Example 5:** Calculate the first derivative of function f given by

__Solution to Example 5:__Function f given above may be considered as the product of functions U = 1/x - 3 and V = (x

^{2}+ 3)/(2x - 1), and function V may be considered as the quotient of two functions x

^{2}+ 3 and 2x - 1. We use the product rule for f and the quotient rule for V as follows

** Example 6:** Calculate the first derivative of function f given by

__Solution to Example 6:__There are several ways to find the derivative of function f given above. One of them is to consider function f as the product of function U = sqrt x and V = (2x - 1)(x

^{3}- x) and also consider V as the product of (2x - 1) and (x

^{3}- x) and apply the product rule to f and V as follows
