The relation between the secant and tangent is used to prove the equation. The detailed description is given below.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The equation is given below.

tan⁵ x = tan ³ x sec² x - tan³ x

Taking tan ³ x common then we have

tan⁵ x = tan ³ x (sec² x - 1)

We know that sec² x - 1 = tan² x, then we have

tan⁵ x = tan ³ x (tan² x)

tan⁵ x = tan⁵ x

Hence proved
