How do I find the value of csc 11π/2? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Nghi N. Oct 23, 2015 Find the value of csc((11pi)/2) Ans: - 1 Explanation: #csc ((11pi)/2) = 1/(sin ((11pi)/2)#. Find #sin ((11pi)/2)# #sin ((11pi)/2) = sin ((3pi)/2 + (8pi)/2) = sin ((3pi)/2) = - 1# Therefor: #csc ((11pi)/2) = 1/(sin) = -1# Answer link Related questions How do you find the trigonometric functions of any angle?
