Full solution stays hidden until you ask for it.
1. Use cosine's period 2pi.
2. Plot maximum, zeros, and minimum over one cycle.
3. Repeat the pattern across the interval.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Starting cosine at 0 when the parent starts at 1.
