" (i) "sin^(-1)(-(1)/(2))

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)) .

Evaluate the following. cos^(-1)(-(1)/(2)) +sin^(-1)(-(1)/(2))

sin [(pi)/(3) - sin^(-1) (-(1)/(2))] is equal to :

sin[(pi)/(2)-sin^(-1)(-(1)/(2))]

sin(3sin^(-1)((1)/(2)))

sin {(pi)/(3) - sin^(-1) ((-1)/(2)) }=…….

tan(1)+cos^(-1)(-(1)/(2))+sin^(-1)(-(1)/(2))

Find the principal values of sin^(-1)((1)/(2)) (b) sin^(-1)(-(1)/(sqrt(2)))
