24.6.6 Setting the Stage for Periodic Change

Core idea

Powers and logs describe one-way rises and falls, but a turning windmill and the ebb and flow of tides need a function that comes back around, which leads us to trigonometry.

Module goal. Unify the roots of equations through a function lens, master the existence theorem for zeros and the bisection method, laying groundwork for continuity and approximation
