Variation

Content

Variation is a connection of sets of numerical values by an equation which indicates some kind of proportionality. We have four major types of variations which are direct, inverse, joint and partial variations.

Direct Variations

Considering two quantities x and y. If when y increases x also increases and when y decreases x also decreases in a constant proportion, then x and y are said to be in direct variation. i.e. x varies directly as y or x is directly proportional to…
