Direct and Inverse Variation Worksheets
What is the Difference Between Direct and Inverse Variations? When you are learning the concepts of variations, confusion may occur. However, with variations being an integral part of mathematics and physics, it is crucial that we wrap our heads around it. Now, two variables can vary either directly or inversely to each other. Whatever the case, there is a nonzero number, which is the constant of variation that separates both entities. Now, for any two variables, if the relation is direct, then y = kx, where k is nonzero constant. However, for any two variables, which are inverse, then y = k/x, where k is the nonzero constant.
