Write parametric equations for a circle of radius 2, centered at the origin that is traced out once in the clockwise direction for 0 ≤ t ≤ 4π. use the module to verify your result. (enter your answer as a comma-separated list of equations. let x and y be in terms of t.)

We know that equation of a circle with origin as it's center is given by

Comparing with we get

Since have a period of 2π but in the given question we need to increase the period to 4π  thus we reduce the argument by 2

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
