Here is a pattern I made with some graphs of trigonometric functions.You can find a copy to print here.
Imagine you had a graphical calculator but the sine button is broken. Can you draw the same patterns using the cosine function instead? Explain how you can transform a cosine graph into a sine graph.
Why not create some trig patterns of your own using graphical calculators or graphing software, and send them to us.
