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

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

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

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

cos^(-1)((-1)/(2))-2sin^(-1)((1)/(2))+3cos^(-1)((-1)/(sqrt(2)))-4tan^(-1)(-1) equals to

cos^(-1)((1)/2)+2sin ^(-1)((1)/(2))=...

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

Find the value of cos^(-1) (-1/2) -2 sin^(-1) (-1/2)

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