Question: \[\tan x - x + c\]...

tan⁡x−x+c\tan x - x + c

A

x+tan⁡x+cx + \tan x + c

B

x−tan⁡x+cx - \tan x + c

C

−x−cot⁡x+c- x - \cot x + c

D

∫ax3+bx2+cx4dx\int_{}^{}{\frac{ax^{3} + bx^{2} + c}{x^{4}}dx}

Answer

−x−cot⁡x+c- x - \cot x + c

Explanation

Solution

−23(1−tan⁡2x)2/3+c- \frac{2}{3}(1 - \tan^{2}x)^{2/3} + c
