What are the six trig function values of (11pi)/4? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Nghi N. Nov 13, 2015 Find the 6 trig function values of (11pi)/4 Explanation: sin ((11pi)/4) = sin ((3pi)/4 + 2pi) = sin ((3pi)/4) = sqrt2/2 cos ((11pi)/4) = cos ((3pi)/4 + 2pi) = cos ((3pi)/4) = -sqrt2/2 tan ((11pi)/4) = sin/(cos) = - 1 cot ((11p)/4) = 1/(tan) = -1 sec ((11pi)/4) = 1/(cos) = 2/sqrt2 = sqrt2 csc ((11pi)/4) = 1/(sin) = -2/sqrt2 = -sqrt2 Answer link Related questions How do you find the trigonometric functions of any angle?
