About this document
Trigonometric Substitution in Integrals by Juan David Vasquez is a document available to read on EtoBox.
This document summarizes trigonometric substitutions that can be used to evaluate integrals of secant, tangent, and cosecant functions. It shows that the integral of secant cubed can be expressed as (secθ tanθ + ln|secθ + tanθ|)/2 + c, using the substitution u = secθ and the identity tan2θ = sec2θ - 1.
