Answer:
1/2 * Log [ Sec 2x ] + integration constant.
Step-by-step explanation:
Integrand function = (1 + tan^2 x ) / [2 Tan x ]
= 1 / tan 2x
= cot 2x = Cot y , where y = 2x and dy = 2 * dx
So the integral becomes
integral 1/2 * Cot y * dy
= 1/2 * [ Log Sec y ] + K using the simple formula for integral of Cot y.
= 1/2 * Log Sec 2x + K
