Graphing Sine and Cosine using the Unit Circle
null
Given y = sin(x), each point on the curve is given by (x, sin(x)).
Each point on the curve y = cos(x) is given by (x,cos(x)).
Investigation: Graph both y = sin(x) and y = cos(x) simultaneously. How is the graph of y = sin(x) related to the graph of y = cos(x)?
