Graphs From the Unit Circle
In this lesson, students use uncooked spaghetti to transfer lengths from the unit circle to a function graph on large butcher paper. In the process, they discover the key features of sine and cosine graphs. The activity is presented for students working in degrees, but another version of the handouts is provided for students working in radians.
Prerequsites for Calculus Quiz
Students will take this self-assessment to make sure they are prepared to take Calculus.
Sine Function (with Unit Circle)
This is an interactive model of the graph of a sine wave in the form y=sin(b). There is a slider that allows the value of "b" (in radian measure) to be changed. The unit circle is shown simultaneously with the graph of the sine function.
