In this lesson, students will learn about the graphs of the four trigonometric functions (tangent, cotangent, secant, and cosecant) by relating them to the sine and cosine graphs. They will understand the patterns, zeros, and asymptotes of each function and how they differ from the sine and cosine functions. By using unit circles and evaluating the trig ratios for specific angles, students will be able to locate asymptotes and understand the behavior of the tangent and cotangent graphs.
