The answer to your question is  sin 3π/2 = -1  and cos 3π/2 = 0

Step-by-step explanation:

Convert 3π/ 2 to degrees

                    π   180°

                  3π/2  x

                    x = (3π/2 x 180)/π

                   x = 270°

In the third quadrant we must look for this information

 sin Ф = opposite side/hypotenuse

 sin 3π/2 = -1/1 = -1

cos Ф = adjacent side/ hypotenuse

 cos 3π/2 = 0/1 = 0

hypotenuse always measures 1 in the unit circle.
