Draw a circle of radius one unit.

Through the centre draw the y- axis and the x-axis.

Mark the coordinates of the points where the axes intersect the circle.

Starting on the x-axis at 0 degrees ,The coordinates are (1,0).

Move anticlockwise along the circle to the point (0,1) which corresponds to 90 degrees.

Continue to the point (-1,0) which is 180 degrees.

Again move to the point (0,-1) which is 270 degrees.

And finally back to (1,0) which is 360 degrees.

For 0 degrees, the x-co-ordinate represents the cosine of 0,and is equal to 1. And the y -co-ordinate which is zero is the sine of 0.
