2.2.8.1. Point Method

In this method, the elasticity of demand is found out at a particular point in the demand curve. For example, at the middle point of the straight line demand curve, elasticity is equal to unity at the higher points of the demand curve, to the left of the middle point, elasticity is more than unity; at lower points, to the right of the middle point elasticity is less than unity; elasticity is infinity at the point, where the demand curve coincides with the Y- axis and the elasticity is zero at the point where the demand curve coincides with the X-axis.
