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?
