Detailed Description

My own Ellipse class.

//////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////////////////

//////////////////////////////////////////////////////// //////////////////////////////////////////////////////// //////////////////////////////////////////////////////// A geometric object for an ellipse with initial centre of mass at (centre_x, centre_y) with axis in the x direction given by 2a and in the y-direction given by 2b. The boundary of the ellipse is parametrised by its angle.
