An equation whose variables are polar coordinates is called a

Answer with explanation:

Polar Equation : An equation whose variables are polar coordinates.

         Polar equation of a curve is denoted in terms of (r, theta).

  Where,

x and y are abscissa and ordinate in x y plane.

Theta is angle made by line joining origin to point represented by , P(r, Theta) in Positive direction of X axis.

⇒r=Distance from origin to the point

Polar equation of Circle

⇒x²+y²=r²

x=r cos A

y=r sin A

Angle , A is made with positive direction of X axis from line joining origin to end point.
