Parametric equations

Parametric equations are a way to represent curves or shapes using equations that define coordinates based on one or more parameters, rather than just relying on traditional x and y coordinates. For example, instead of describing a circle with a single equation (like x² + y² = r²), parametric equations express the position of points on the circle using separate equations for x and y based on a parameter, typically time (t). This approach allows for more flexibility in describing complex shapes and motions, making it easier to model real-world phenomena in fields like physics, engineering, and computer graphics.
