• Use the unit circle (paper plate) that was saved from the unit circle lesson. • Wrap a piece of yarn around the circle, and mark each of the main values on the yarn with a marker. Trigonometric Graphs - Activity

• Put a straight line across two pieces of paper, and transfer the radian measures from the piece of yarn • Label each mark appropriately Trigonometric Graphs - Activity

• Break pieces of spaghetti to the length of the y value (sine) for each graph marking. • Glue these pieces onto your paper at the appropriate locations • Be sure to show the third and fourth quadrants as negative. Trigonometric Graphs - Activity

• With another piece of yarn, or a marker, connect all the tops of the spaghetti with a smooth line. Let the glue dry Trigonometric Graphs - Activity
