Introduction to Sine, Cosine, and Tangent Functions and Their Graphs

The video tutorial covers the unit circle and its role in defining trigonometric functions: sine, cosine, and tangent. It explains how these functions are derived from the unit circle and demonstrates their graphical representations. The tutorial also discusses the transformations of these trigonometric graphs, including scaling and translation, and their effects on the graphs' shapes.
