Alg 2 - Creating Graphs of Sine, Cosine, and Tangent from a Unit Circle
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) adjacent to an rx plane. Using the value of r and the x coordinate for each point on the unit circle, students create a graph of thirteen points on y = sin r. They are then asked to draw a smooth curve
