`sin^(-1)[cos((2 pi)/3)]`

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

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

cos^(-1)(cos(5 pi/(3))+sin^(-1)(cos(5 pi/(3))=

Evaluate each of the following: sin^(-1)(sin(pi)/(3)) (ii) cos^(-1)(cos(2 pi)/(3))tan^(-1)(tan(pi)/(4))(iv)sin^(-1)(sin(2 pi)/(3))cos^(-1)(cos(7 pi)/(7))(vi)tan^(-1)(tan(3 pi)/(4))sin^(-1)(cos(-600^(@))cos^(-1)(cos(-680^(@)))

Evaluate the following: 1*sin^(-1)(sin(2 pi)/(3))2cos^(-1)(cos(7 pi)/(6))3*tan^(-1)(tan(2 pi)/(3))

cos^(-1)(cos((5 pi)/(3)))+sin^(-1)(sin((5 pi)/(3)))=

The value of cos ^(-1)""[cot ((pi)/(2))]+cos^(-1)""[sin ((2pi)/(3))] is

Find the value of cos^(-1) ( cos . (2pi)/3) + sin^(-1) ( sin . (2pi)/3) .
