Find the solutions of each equation on the interval [0,2pi)
sin(3pi/2+ x)+sin(3pi/2 +x)= -2

Answer:
x=0
Step-by-step explanation:
You can combine the equation to get 2sin(3/2 +x) = -2
divide both sides by 2 and you get the equation equal to -1. sin is equal to -1 when the value inside is 3/2 so this is the answer.
