Compute the exact solutions of the equation which are in the interval [0,2π). If there is no solution or the value is not defined, then use NO! as your answer. cos(9θ)=9 θ= (List all of the solutions in the interval [0,2π), separated by commas.)

Step 1
First, we need to recognize that the equation cos(9θ) = 9 is not solvable in the real numbers, since the cosine function only takes values between -1 and 1. Show more…
