Given the equation cos x = 0.7, find only the solutions that are in the interval [−2π, 4π]. Round to nearest 0.01.

So far the solutions I have found are 3.94, -2.35, and 10.22. I don't know if these are right or if there are more solutions to be found, because everything else I find is too big or too small for the interval.
