there are three methods of measuring elasticity of demand
According to this method the degree of elasticity of demand is measured by comparing firm's revenue from consumer's total outlay on the goods before the change in the price with after the change in the price.
Two common methods for calculating elasticity of demand are the percentage change method and the point elasticity method. The percentage change method involves dividing the percentage change in quantity demanded by the percentage change in price. The point elasticity method, on the other hand, uses calculus to calculate elasticity at a specific point on the demand curve, typically by taking the derivative of the demand function and multiplying it by the price-quantity ratio. Both methods provide insight into how sensitive consumers are to price changes.

The point method measure price elasticity of demand at different point on a demand curve .
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Unitary elasticity is when the price elasticity of demand is exactly equal to one.
The proportionate method of measuring price elasticity calculates the responsiveness of quantity demanded or supplied to changes in price by comparing the percentage change in quantity to the percentage change in price. It is expressed as the ratio of the percentage change in quantity to the percentage change in price, resulting in the price elasticity of demand or supply coefficient. This method allows for a straightforward interpretation of elasticity, where values greater than 1 indicate elastic demand, values less than 1 indicate inelastic demand, and a value of 1 indicates unitary elasticity.
distinguish between price elasticity of demand and income elasticity of demand
under total otlay method basically there are 3 other sub methods with the help of which you can calculate the price elasticity of demand.they are: elasticity greater than unity...ep>1 elasticity less than unity,,,,,,,ep<1 elasticity equals to unity....ep=1
