In this lesson, we will learn how to sketch the graphs of the six trigonometric functions. We will begin with sine and cosine. We will begin with a basic graph for each and then learn how to sketch the graph when transformations are involved. Then we will move into how to graph tangent, cotangent, secant and cosecant.
