# Derivative of Parametric Functions

The derivative of parametric functions is a crucial concept in calculus, allowing us to analyze the rate of change of quantities that vary with respect to a third parameter. In parametric equations, each variable is expressed as a function of an independent parameter, often denoted as t. Understanding how to find the derivative of such functions enables us to determine instantaneous rates of change, velocities, and slopes of curves traced by parametric equations. This introduction sets the stage for exploring the methodology and applications of differentiating parametrically defined functions, providing a foundational understanding essential in various fields of mathematics and science.
