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(3θ)=12 θ= (List all of the solutions in the interval [0,2π), separated by commas.)
Added by Alfonso G.
Step 1
First, we need to recognize that the range of cosine is [-1,1], which means that there is no real number x such that cos(x) = 12. Show more…
