Use the unit circle to find the value of sin 3pi/2 and cos 3pi/2

Step-by-step explanation:

First, determine the point on the unit circle which corresponds to angle (that is 270° in degrees)

Start from point (1,0) - this point represents angle 0.

Point (0,1) represents angle (that is 90° in degrees) point (-1,0) represents angle (that is 180° in degrees) and point (0,-1) represents angle

The first coordinate of this point is the value of cosine, then

the second coordinate is the value of sine, then
