Find the principal value of each of the following: (i) sin^(-1)(-(sqrt(3))/2) (ii) sin^(-1)(cos (pi/3)) (iii) sin^(-1)((sqrt(3)-1)/(2sqrt(2)))

Find the principal value of each of the following: sin^(-1)(-(sqrt(3))/(2))( (ii) sin^(-1)((cos(2 pi))/(3))( iii) sin^(-1)((sqrt(3)-1)/(2sqrt(2)))

Write the principal value of cos^(-1)(cos((2pi)/3))+sin^(-1)(sin((2pi)/3))

Prove that (i) " sin " .(pi)/(6). " cos " .(pi)/(6) = (sqrt(3))/(4) " " (iii) cos^(2) .(pi)/(2) - sin^(2) .(pi)/(2) =(sqrt(3))/(2)

Write the principal value of cos^(-1)(cos(2 pi)/(3))+sin^(-1)(sin(2 pi)/(3))

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

What is the value of cos^(-1)(cos((2pi)/3))+sin^(-1)(sin((2pi)/3)) ?
