Trace the cosine curve using a Unit Circle by having the trace on then moving point C on the circle.
The circle with centre A is a unit Circle.
The coordinates of any point C on it are (cos BAC, sin BAC)
By plotting the valuse taken by the angle BAC on the X axis and
Plotting the valuse taken by cos of angle BAC, i.e x coordinate of C on the Y axis
We get the curve for the function y =cos x as takes values from 0 to 2 pi.
