Simplify :
`tan^(-1)(1) - cos^(-1) ((-1)/2) +sin^(-1) ((-sqrt(3))/2)`

1. sin^(-1) (-1/2) = 2. tan^(-1) (-sqrt3) =

sin[cos^(-1)(-1/2)+tan^(-1)(sqrt(3))]

Evaluate the value of tan^(-1) (-sqrt(3)) +cos^(-1) (1/(sqrt(2))) + sin^(-1) (-(sqrt(3))/2)

Evaluate: tan ^ (- 1) 1 + cos ^ (- 1) ((1) / (2)) + sin ^ (- 1) (- (1) / (2)) + tan ^ (- 1) ( -sqrt (3)) - sec ^ (- 1) (- 2) + cos ec ^ (- 1) ((2) / (sqrt (3)))

Simplify tan[(1)/(2)cos^(-1)((3)/(sqrt(11)))]

The value of sin ^(-1) (-(1)/(sqrt2)) + cos ^(-1) (-(1)/(2)) - tan ^(-1) (-sqrt3) + cot ^(-1) (-(1)/(sqrt3)) is

The value of sin ^(-1) (-(1)/(sqrt2)) + cos ^(-1) (-(1)/(2)) - tan ^(-1) (-sqrt3) + cot ^(-1) (-(1)/(sqrt3)) is

tan^(-1)(2)=sin^(-1)(2/(sqrt(5)))=cos^(-1)(1/(sqrt(5)))

Find the principal of : (1) sin ^(-1)((1)/(2)) (2) tan^(-1)(-sqrt(3)) (3) cos^(-1)(-(1)/(sqrt(2))) (4) sin^(-1)(-(1)/(2)) .
