" 4.Evaluete "cosec(cos^(-1)(17)/(13))

Evaluate "cos"("cosec"^(-1)13/12) .

"cosec"(sin^(-1)x+cos^(-1)x)

Evaluate: sin(cos^(-1)(3)/(5)+csc^(-1)(13)/(5))

Evaluate each of the following: cos((cos^(-1)5)/(13))( ii) cos((sin^(-1)8)/(17))( iii) cos((tan^(-1)3)/(4))

cos^(-1)(8/17)-cos^(-1)(5/13)=

tan (CSC ^ (- 1) (13) / (12))

The value of cot("cosec"^(-1)5/3+tan^(-1)""(2)/3) is a) 6/17 b) 3/17 c) 4/17 d) 5/17

sin^(-1)""(3)/(5)-cos^(-1)""(12)/(13)+sec^(-1)""(5)/(3)-cosec^(-1)(13)/(12) is equal to
