Integrate the following functions with respect to x :

12th Maths RBSE Solution Question 1.
[1+2 tan x (tan x + sec x)]
Solution:
∫ [1 + 2 tan x (tan x + sec x)] dx
= ∫ [1 + 2 tan2 x + 2 tan x sec x] dx
= ∫ [2(1 + tan2 x) + 2 sec x tan x -1] dx
= 2 ∫ (sec2 x + sec x tan x) dx – ∫ dx
= 2(tan x + sec x) – x + C
