Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs of sine and cosine are related to the unit circle. Transformations of Functions 1.3 An applet illustrating how transformations ...

Due to the similarity between sine and cosine functions, transformations of y = cos (x) to y = a cos (n x − b) + c have the same effects as transformations of y = sin (x) to y = a sin (n x − b) + c.
