{\cos ^{ - 1}}\left( {\frac{{ - 1}}{2}} \right) - 2{\sin ^{ - 1}}\left( {\frac{1}{2}} \right) + 3{\cos ^{ - 1}}\left( {\frac{{ - 1}}{{\sqrt 2 }}} \right)\;\; - 4{\tan ^{ - 1}}\left( { - 1} \right)

equals

View answer and explanation

Correct option: C

\frac{{47\pi }}{{12}}

Option D (

\frac{{43\pi }}{{12}}

) is correct because by evaluating each inverse trigonometric function and simplifying the expression, the result is

\frac{{43\pi}}{{12}}
