Question
$\int \frac{\sec x d x}{\sqrt{\sin (2 x+a)+\sin a}}=k \sqrt{\tan x+\tan a}+C$,where $k=$(A) $\sqrt{\frac{2}{\cos a}}$(B) $\sqrt{2 \cos a}$(C) $\sqrt{\cos a}$(D) $\sqrt{\frac{1}{\cos a}}$
Step 1
Step 1: We are given the integral $\int \frac{\sec x dx}{\sqrt{\sin (2 x+a)+\sin a}}=k \sqrt{\tan x+\tan a}+C$ and we need to find the value of $k$. Show more…

$\int \frac{\sqrt{\cot x}-\sqrt{\tan x}}{1+3 \sin 2 x} d x$ $=k \tan ^{-1}\left(\frac{\sqrt{\tan x}+\sqrt{\cot x}}{2}\right)+C$ where $k=$ (A) 1 (B) $-1$ (C) 2 (D) $-2$
$\int \frac{\cos x}{1-\sin x \cos x} d x=\tan ^{-1}(\sin x-\cos x)$ $+\frac{k}{\sqrt{3}} \ln \left|\frac{\sin x+\cos x-\sqrt{3}}{\sin x+\cos x-\sqrt{3}}\right|+C$, where $k=$ (A) $-\frac{1}{x}$ (B) $\frac{1}{2}$ (C) $-1$ (D) 1
If $\left.\int \sqrt{[}(1-\sqrt{x}) /(1+\sqrt{x})\right] d x=k \sin \left(\cos ^{-1} \sqrt{x}\right)$ $+\left[\left\{\sin \left(2 \cos ^{-1} \sqrt{x}\right)\right\} / 2\right]+\cos ^{-1} \sqrt{x}+c$ then $k=$ (a) 1 (b) 2 (c) $-1$ (d) $-2$
