You can put this solution on YOUR website! An equation is given. (Enter your answers as a comma-separated list. Round terms to three decimal places where appropriate. If there is no solution, enter NO SOLUTION.)
− 2/sqr3 cos 3θ = 1
(a) Find all solutions of the equation.
(b) Find the solutions in the interval [0, 2π).
**
− 2/√3 cos 3θ = 1
cos 3θ = -√3/2
3θ =2.618, 3.665 (in quadrants II and III where cos<0)
θ=0.872, 1.222
