👉 Parameterizing a mathematical expression is a process of specifying what variable(s) will be used in a formula or equation. In other words, it involves defining the variables that you are interested in using in a particular formula or equation. For example, if you are working with a system of linear equations, you might parameterize them by setting one of the variables to a specific value and then solving for the others. The goal is to ensure that the solution to the resulting equation is unique, meaning that it
