Question 921234: Simplify the expression algebraically and use a graphing utility to confirm your answer graphically.
cos(3π/2− x)
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
cos(3π/2) = 0, sin(3π/2) = -1
cos(-θ) = cos θ
cos(3π/2− x) = cos( x - 3π/2) = - [cos(x)(0) + sin(x)(-1) = -sin(x)
..........
Confirmed graphically
