Trigonometric Functions and Their Properties

The video tutorial covers the sine, cosine, and tangent graphs, explaining their key features, symmetry, and periodicity. It begins with a review of sine and cosine rules, then delves into the characteristics of each trigonometric graph, including their symmetry and range. The tutorial also explores how to calculate specific values using these graphs and discusses the concept of asymptotes in the tangent graph.
