In this lesson, we will discover parametric equations and how we will use the parameter to model certain functions and situations. We will also take a look at how to eliminate the parameter to ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the ...
