The value of $tan^{-1}\sqrt{3}-sec^{-1}(-2)+cosec^{-1}\frac{2}{\sqrt{3}}$, is
Answer & explanation
Correct answer: option 3
$tan^{-1}\sqrt{3}-sec^{-1}(-2)+cosec^{-1}\frac{2}{\sqrt{3}}=\frac{\pi}{3}-\frac{2\pi}{3}+\frac{\pi}{3}=0$
The value of $tan^{-1}\sqrt{3}-sec^{-1}(-2)+cosec^{-1}\frac{2}{\sqrt{3}}$, is
Correct answer: option 3
$tan^{-1}\sqrt{3}-sec^{-1}(-2)+cosec^{-1}\frac{2}{\sqrt{3}}=\frac{\pi}{3}-\frac{2\pi}{3}+\frac{\pi}{3}=0$
