sec^(-1)(2sin(3 pi)/(4))

Find the principal values of each of the following: sec^(-1)(2sin(3pi)/4) (ii) sec^(-1)(2tan(3pi)/4)

Find the principal values of each of the following: sec ^(-1)(2(sin(3 pi))/(4))( ii) sec^(-1)(2(tan(3 pi))/(4))

Evaluate each of the following: sec^(-1)((sec pi)/(3)) (ii) sec^(-1)((sec(2 pi))/(3))( iii) sec^(-1)((sec(5 pi))/(4))

Simplify (I ) cos ^(-1) ( cos ((13 pi )/(3))) (ii ) tan^(-1) ( tan ((3pi)/(4))) (iii ) sec^(-1) ( sec ((5pi )/(3))) (iv ) sin^(-1) [ sin 10 ]

Evaluate each of the following: sec^(-1)(secpi/3) (ii) sec^(-1)(sec(2pi)/3) (iii) sec^(-1)(sec(5pi)/4)

4sin ((pi) / (6)) sin ^ (2) ((pi) / (3)) + 3cos ((pi) / (3)) tan ((pi) / (4)) + cos e ^ ( 2) ((pi) / (2)) = 2sec ^ (2) ((pi) / (4))
