This calculator computes the distance between two points in two or three dimensions. It also finds the distance between two places on the world map, which are determined by their longitude and latitude. The calculator shows formulas and all steps.
Price elasticity of demand on certain interval of graph = percentage of change of quantity demanded over interval / percentage of change of price over interval. Note: price elasticity is not the same as slope. Slope remains the same on a straight line graph but elasticity changes.

To calculate elasticity, we will use the average percentage change in both quantity and price. This is called the midpoint method for elasticity and is represented by the following equations: [latex]\displaystyle\text{percent change in quantity}=\frac{Q_2-Q_1}{(Q_2+Q_1)\div{2}}\times{100}[/latex]
