Question

What is the value of. tan^ -1 (1/√3) -sin^-1 (1) +cos^-1 (1/2)

Answer 1

Answer:

180⁰

Step-by-step explanation:

$\tan^{-1}{\big(\frac{1}{\sqrt{3}}\big)} - \sin^{-1}{(1)}+\cos^{-1}{\big(\frac{1}{2}\big)}\\ \\ =30^o + 90^o+60^o\\ \\ =180^o$

Answer 2

${ \tan}^{ - 1} ( \frac{1}{ \sqrt{3} } ) - { \sin}^{ - 1} (1) + { \cos}^{ - 1} ( \frac{1}{2} )$

$\sf =( \sqrt{3} ) - 1 + 2 = 1 + \sqrt{3}$
