tan((11 pi)/(12))

tan((11pi)/12)

Find the values of the following trigonometric ratio: (tan(11 pi))/(6)

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))

If p= tan(-(11pi)/(6)).q=tan((21pi)/(4)) and r=cot ((383pi)/(6)) , then which of the following is/are correct? 1.The value of pxxr is 2 2.p.q and r are in G.P Select the correct answer using the code given below:

tan((pi)/(24))tan((3 pi)/(24))tan((5 pi)/(24))tan((7 pi)/(24))tan((9 pi)/ (24))tan((11 pi)/(24))tan((16 pi)/(24))

cos ((5pi)/(4)) - sin ((5pi)/(4)) + tan((11pi)/(4)) - cot((11pi)/(4))=

"tan"^(2)(pi)/(4) "sin"(pi)/(3) "tan"(pi)/(6) "tan"^(2)(pi)/(3) =
