Differentiation of sec x: The derivative of sec x

The derivative of sec x with respect to x is written as d/dx(sec x) and it is equal to sec x tan x. Let us learn more about the differentiation of sec x along with its formula, proof by different methods, and a few solved examples. Learn how to differentiate Sec x using the first principle, chain rule and quotient rule. Find the formula for Sec x and its applications in trigonometry and calculus. The derivative of sec x with respect to x is equal to secx tanx. We will prove this by first principle, chain rule and quotient rule of derivatives.
