1. `sin^(-1) (1/sqrt2)`
2. `cos^(-1) (sqrt3/2)`

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

(a) sin^(-1)(-1/2)=? (b) cos^(-1)(sqrt3/2)=?

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

sin(cos^(-1)(-sqrt3/2))=?

Prove that tan^(-1).(1)/(sqrt2) + sin^(-1).(1)/(sqrt5) - cos^(-1).(1)/(sqrt10) = -pi + cot^(-1) ((1 + sqrt2)/(1 - sqrt2))

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

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

For the principal values,evaluate each of the following: sin^(-1)(-(1)/(2))+2cos^(-1)(-(sqrt(3))/(2))( ii) sin^(-1)(-(sqrt(3))/(2))+cos^(-1)((sqrt(3))/(2))

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

sin[cos^(-1)(-1/sqrt2)]=?
