Are you curious to know what is the derivative of sec2x? You have come to the right place as I am going to tell you everything about the derivative of sec2x in a very simple explanation. Without further discussion let’s begin to know what is the derivative of sec2x?

In the realm of calculus, trigonometric functions present fascinating challenges and intricate derivatives. Among these functions, the derivative of secant squared, often denoted as sec²(x), demands careful calculation and understanding. Delving into the intricacies of trigonometric differentiation, let’s unravel the process of finding the derivative of sec²(x) step by step.

## What Is The Derivative Of Sec2x?

The secant function, sec(x), represents the reciprocal of the cosine function, 1/cos(x). When squared, sec²(x) signifies the square of this reciprocal function, raising it to the power of 2.

The derivative of sec²(x) requires applying the chain rule of differentiation, which involves two fundamental steps:

- Derivative of Outer Function: Begin by identifying the outer function, in this case, sec²(x), and differentiating it with respect to its inner function.
- Derivative of Inner Function: Proceed to calculate the derivative of the inner function, which involves differentiating the argument inside the secant function.

## Derivative Calculation Of Sec²(X):

- Identifying the Outer Function: The outer function in this scenario is sec²(x).
- Differentiating the Outer Function: Applying the chain rule, the derivative of sec²(x) involves treating sec(x) as the inner function. The derivative of sec²(x) with respect to x can be expressed as:

d/dx [sec²(x)] = 2 * sec(x) * sec(x) * tan(x)

Here, the derivative of sec(x) is sec(x) * tan(x), and multiplying by 2 and an additional sec(x) gives us the final derivative expression.
