1) Point elasticity is measured by the ratio of the lower segment of the curve below the given point to uppa segment the super part of the curve above the point. 2) Arc elasticity is measured by the use of mid point between the old & the new figures in the case of both prine and qualitiy demonded.

∙ 9y agoArc elasticity is used to measure the elasticity at the midpoint of two different points. Point elasticity on the other hand, is used to measure the elasticity of demand at a particular point of the demand curve. Point elasticity can also measure the elasticity between two points of a demand curve.

What is the difference that exists between arc elasticity of demand and point elasticity of demand?
Arch elasticity demand is the percentage change in one variable divided by the percentage change in another variable, it calculates the elasticity over a range of values, while point elasticity of demand uses differential calculus to determine the elasticity at a specific point
Methods of calculating price elasticity of demand?
(1) Total outlay or Expenditure Method (2) Proportionate or Percentage Method (3) Point Elastic Method (4) Arc Elasticity of Method (5) Revenue Method

Arc elasticityFrom Wikipedia, the free encyclopediaJump to: navigation, searchArc elasticity is the elasticity of one variable with respect to another between two given points.The y arc elasticity of x is defined as:where the percentage change is calculated relative to the midpointThe midpoint arc elasticity formula was advocated by R. G. D. Allen due to the following properties: (1) symmetric with respect to the two prices and two quantities, (2) independent of the units of measurement, and (3) yield a value of unity if the total revenues at two points are equal.[1]Arc elasticity is used when there is not a general function for the relationship of two variables. Therefore, point elasticity may be seen as an estimator of elasticity; this is because point elasticity may be ascertained whenever a function is defined.For comparison, the y point elasticity of x is given by:[edit] Application in economicsThe P arc elasticity of Q is calculated asThe percentage is calculated differently from the normal manner of percent change. This percent change uses the average (or midpoint) of the points, in lieu of the original point as the base.[edit] ExampleSuppose that you know of two points on a demand curve (Q1,P1) and (Q2,P2). (Nothing else might be known about the demand curve.) Then you obtain the arc elasticity (a measure of the price elasticity of demand and an estimate of the elasticity of a differentiable curve at a single point) using the formulaSuppose we measure the demand for hot dogs at a football game. Let's say that after halftime we lower the price, and quantity demanded changes from 80 units to 120 units. The percent change, measured against the average, would be (120-80)/((120+80)/2))=40%.Normally, a percent change is measured against the initial value. In this case, this gives (12-8)/8= 50%. The percent change for the opposite trend, 120 units to 80 units, would be -33.3%. The midpoint formula has the benefit that a movement from A to B is the same as a movement from B to A in absolute value. (In this case, it would be -40%.)Suppose that the change in the price of hot dogs was from $3 to $1. The percent change in price measured against the midpoint would be -100%, so the price elasticity of demand is (40%/-100%) or -40%. It is common to use the absolute value of price elasticity, since for a normal (decreasing) demand curve they are always negative. Thus the demand of the football fans for hot dogs has 40% elasticity, and is therefore inelastic.
How do you calculate arc elasticity of a commodity?
You calculate the arc elasticity of a commodity by dividing the change in demand by the average price, and then dividing that answer by the change in price divided by the average demand. So you will have (change in demand/average price)/(change in price/average demand).
Calculation of arc elasticity of demand?
((Q1-Q0)/average of Q0 and Q1) over ((P1-P0)/average of P0 and P1)

What is the difference between the center of an arc and the midpoint of an arc?
there is not much difference
What is the difference between an arc and an angle?
An angle is measurement use to tell the distance between two lines that are concurrent at a point. An arc is the length of a curve drawn with a unchanging distance (radius length) around a point..
What is the difference between Arc tan and arc tan?
There is no difference in meaning between the two. It is usually spelled in lowercase, though (arc tan, or arctan).

What is the difference between the measure of an arc and arc length?
They are normally the same. However, the measure of the arc could refer to the angle subtended at the centre of the radius of curvature.
