# Trigonometric Functions-Graphs

In this worksheet you will use the definition of the t- functions to plot the graphs of all six trigonometric functions. The first applet is for you to explore and observe how the graph of sine function is formed. In the other applet you will plot graph of cosine, tangent , secant and cosecant function as a point moves around unit circle.
