The equations x = a cos ф, y = b sin ф taken together are called the parametric equations of the ellipse **x2a2 + y2b2 = 1**; where ф is parameter (ф is called the eccentric angle of the point P).What Is Perimeter of Ellipse? The perimeter of ellipse is **the length of the continuous line forming the boundary of the ellipse**. Unfortunately, unlike other shapes, there is no formula to calculate the exact (or) accurate value of the perimeter of an ellipse, or any other figure of the conic section.Converting from rectangular to parametric can be very simple: given y=f(x), the parametric equations **x=t, y=f(t)** produce the same graph. As an example, given y=x2, the parametric equations x=t, y=t2 produce the familiar parabola. However, other parametrizations can be used.

## What is meant by parametric function?

Summary. **A function with a one-dimensional input and a multidimensional output can be thought of as drawing a curve in space**. Such a function is called a parametric function, and its input is called a parameter. Sometimes in multivariable calculus, you need to find a parametric function that draws a particular curve.
