Question

$\text{cosec}x\cot x + c$

• A. $\int_{}^{}{\{ 1 + 2\tan x(\tan x + \sec x)\}^{1/2}dx =}$
• B. $\log(\sec x + \tan x) + c$
• C. $\log(\sec x + \tan x)^{1/2} + c$
• D. None of these

Answer 1

Answer: (B)

$\log(\sec x + \tan x) + c$

Answer 2

${logtan}\theta + \frac{1}{2}\tan^{2}\theta + c$

$\int_{}^{}{\frac{1}{\cos^{- 1}x.\sqrt{1 - x^{2}}}dx =}$.
