鈭�secmxtannxdx,meven

Short Answer

Expert verified

Use the formula:sec2x=1+tan2x

Step by step solution

01

Step 1. Given information

Integral is鈭�secmxtannxdx,meven

02

Step 2. Explanation

Consider the integral 鈭�secmxtannxdx,meven

Write secmx=sec2xsecm-2x, then use the formula sec2x=1+tan2x

Then lettanx=uand use the formulatanx'=sec2x
