50 tan(3 tan^-1 ( 12 )+2 cos^-1 ( 1 5 ))+4 2 tan ( 12 tan (2 2 ) ) is equal to_____.

Question

Accepted Answer

Correct answer: 29. (29) 50 tan(3 tan^-1 12+2 cos^-1 1 5)+4 2 tan ( 12 tan^-12 2 ) =50 tan( tan^-1 12+2( tan^-1 12+ tan^-12))+4 2 tan ( 12 tan^-12 2 ) =50 tan( tan^-1 12+2. 2)+4 2 1 2 =50 ( tantan^-1 12 )+4 = 25 +4 = 29

$50 tan (3 tan^{- 1} (\frac{1}{2}) + 2 cos^{- 1} (\frac{1}{5})) + 42 tan (\frac{1}{2} tan (22)) is equal to_____.$
