list solutions to periodic equations

Having had a look at PeriodicAnswers1 for how to formulate question so that a student can give any answer to periodic equation. I was wondering if anyone has authored or has any insight into authoring trig questions where the answer(s) would be a list of solutions for a particular interval of the function argument. For example

calculate all the solutions to cos(\theta) = 1/2 for -2\pi < \theta < 2\pi
