Explanation Graph of an ellipse where a > b is given below: From the above graph where a > b , we find that the curvature is maximum when t = 90 degrees or 180 degrees i.e. minimum when t = π 2 , 3 π 2 And maximum in the horizontal vertices i.e. when t = 0 , π This can be confirmed from equation 10 as follows: Equation (1) says that Curvature = a b ( a 2 sin 2 t + b
