Rearranging Elasticity Formulas and the Elasticity Triangle

The video tutorial explains how to rearrange elasticity formulas, focusing on price elasticity of demand. It provides examples of calculating elasticity and demonstrates how to rearrange formulas to solve different problems. The concept of the elasticity triangle is introduced, showing how it can be used to calculate various elasticities, including price elasticity of supply, income elasticity of demand, and cross elasticity of demand.
