Question: \(x^{3} - 4\sqrt{x} + c\)...

x3−4x+cx^{3} - 4\sqrt{x} + c

A

∫dx1+sin⁡x=tan⁡(x2+a)+b\int_{}^{}{\frac{dx}{1 + \sin x} = \tan\left( \frac{x}{2} + a \right) + b}

B

a=π4, 6mub=3a = \frac{\pi}{4},\mspace{6mu} b = 3

C

a=−π4, 6mub=3a = - \frac{\pi}{4},\mspace{6mu} b = 3

D

a=π4, 6mub=a = \frac{\pi}{4},\mspace{6mu} b =

Answer

∫dx1+sin⁡x=tan⁡(x2+a)+b\int_{}^{}{\frac{dx}{1 + \sin x} = \tan\left( \frac{x}{2} + a \right) + b}

Explanation

Solution

log⁡(1+ex)−x+e−x+c\log(1 + e^{x}) - x + e^{- x} + c

log⁡(1+ex)+x+e−x+c\log(1 + e^{x}) + x + e^{- x} + c
