" W) "cosec^(-1)((-2)/(sqrt(3)))

Find the principal value of "cosec"^(-1)(2/(sqrt(3)))

Find the principal values of cosec^(-1)(2) and cosec^(-1)(-(2)/(sqrt(3)))

Find the value of : sec"cosec "^(-1) ((2)/(sqrt(3)))

Find the values of the following: cosec^(-1)(2/(sqrt(3)))

cosec"^(-1)(-sqrt(2))

cosec"^(-1)(-sqrt(2))

For the principal values,evaluate the following: sin^(-1)(-(sqrt(3))/(2))+csc^(-1)(-(2)/(sqrt(3)))sec^(-1)(sqrt(2))+2csc^(-1)(-sqrt(2))sin^(-1)[cos{2csc^(-1)(-2)}]csc^(-1)(2tan(11 pi)/(6))

Evaluate the following : tan ( cosec^(-1) 2/sqrt(3))
