Question

Solve each equation on the interval [0,2π].

1. 4sin^2x-3=0

Part A: Solve each equation separately to get the full solution set, choosing only solutions on the interval [0,2π].

2. cos(3x)=-1

Part I: Solve this equation for 3x, finding all values on the interval [0,2π], that satisfy the equation.

Part II: Use algebra to find all the values of x between 0 and 2π that satisfy this equation.
