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

Find the values of : (1) cos^(-1)((1)/(2))+tan^(-1)((1)/sqrt(3)) (2) cos^(-1)((1)/(2))+2sin^(-1) ((1)/(2)) (3) cosec ^(-1)(-sqrt(2))+cot^(-1)(sqrt(3)) .

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))

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

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

If quad Tan^(-1)(1)+cos^(-1)(-(1)/(2))+sin^(-1)(-(1)/(2)) and y=cos[(1)/(2)cos^(-1)((1)/(8))] then

cos[2cos^(-1)((1)/(5))+sin^(-1)((1)/(5))] =

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

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

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