Wired Faculty App

Evaluate: $\int \frac{\cos 2 x + 2 \sin^{2} x}{\cos^{2} x} dx$

Name: Wired Faculty - The Best Learning App
Rating: 4.6 (1864 reviews)

Solution

$I = \int \frac{\cos 2 x + 2 \sin^{2} x}{\cos^{2} x} dx I = \int \frac{1 - 2 \sin^{2} x + 2 \sin^{2} x}{\cos^{2} x} I = \int \sec^{2} x dx I = \tan x + C$
