Parametric and Polar Equations , a function with two variables, x and y. In some cases, though it is useful to introduce a third variable, called a parameter, and express x and y in terms of the parameter.
Polar equations ,work. Coordinates in polar equations are of the form (r,θ), where r represents radius and θ represents angle.
Hence both are same type of equation. One with t parameter and another with θ
Polar and parametric
