This non-calculator activity will engage the students in creating the graphs for y = sin r,
y = cos r and y = tan r from the unit circle for values of 0 ≤ r ≤ 2π.
• To graph the function y = sin r students are given a unit circle (divided into sixteen parts to match with π/6, π/3, π/4, π/2, etc)
Using manipulatives, students develop the angle measure, the radian measure, and the xy-coordinates for each point around a unit circle.
The package includes one unit circle and 12 special right
triangles and a chart. Using the unit circle that the students will develop, students can fill in the
This graphing calculator activity engages the students in building a unit circle and then connecting the points around the unit circle with the graphs of the six trigonometric functions. Many teachers do not know they can create this visual on a TI-84 graphing calculator and then use the trace feat
This activity describes how you can fold a circle or a large paper plate to form a unit circle.
• The first fold creates the diameter of the circle
• While the circle is folded it is folded in half again creating a second diameter that is perpendicular to the first diameter
• Students begin by wri
