How to Find the Derivative of sec(x) using the Quotient Rule in Calculus

derivative of secx

To find the derivative of sec(x), we can use the quotient rule

To find the derivative of sec(x), we can use the quotient rule.

First, let’s define sec(x):

sec(x) = 1 / cos(x)

Now, let’s find the derivative:

Let f(x) = sec(x)

Using the quotient rule, the derivative of f(x) is given by:

f'(x) = (cos(x) * (0) – (1) * (-sin(x))) / (cos(x))^2

Simplifying, we get:

f'(x) = sin(x) / (cos(x))^2

This is the derivative of sec(x) with respect to x.
