What are the critical points of a sine and cosine graph

The video tutorial explains critical points in sine and cosine graphs, focusing on X intercepts, maximum, and minimum points. It covers sketching these graphs from 0 to 2π and identifies critical points. The tutorial discusses how transformations affect these points and provides a method to calculate distances between them by dividing the period by four. This understanding aids in plotting graphs accurately despite transformations.
