.
Circle of the radius of 3 units, centered at the origin of the (x,y) coordinate plane.
When " t " changes from 0 to radians, the point (x,y) makes precisely three full rotations clockwise
along the circle, starting from the position 12:00 ( 3 units vertically up, or (0,3) ).

Square the expressions for both x and y and then use the Pythagorean identity
The equation is
which you surely know is a circle with center at the origin and radius 3.
