How do we find the period of our trigonometric graphs sine and cosine

The video tutorial explains the concept of the period in trigonometric graphs, focusing on sine and cosine functions. It uses the unit circle to demonstrate how these graphs repeat their values over a cycle. The tutorial covers the concept of periodicity, coterminal angles, and how to graph the cosine function. It also explains how to calculate the period of sine and cosine functions, especially when transformations are applied, by using the formula 2π divided by the coefficient B in the function's equation.
