Co ordinate geometry : - ( Equation of tangent and normal to an ellipse ) - 107.

Co ordinate geometry is one of the most important and exciting ideas of mathematics. It provides a connection between algebra and geometry through graphs of lines and curves. The Conic section is the intersection of a plane and a cone. An ellipse is the locus of a point which moves so that its distance from a fixed point (focus) bears a constant ratio to its fixed straight line (directrix). This ratio is called eccentricity e .It is always less than 1. Equation of tangent and normal to an ellipse.
