Ex 7.2, 39 2 2 equals tan x + cot x + C (B) tan x cot x + C (C) tan x cot x + C (D) tan x cot 2x + C Step 1: Simplify the given function sin 2 cos 2 = 1 sin 2 cos 2 . = sin 2 + cos 2 sin 2 cos 2 . = sin 2 sin 2 cos 2 . + cos 2 sin 2 cos 2 . = 1 cos 2 . + 1 sin 2 . = sec 2 . + 2 . = tan + 1 cot + 2 = tan cot + Option B is correct.
