Answer to Question #250738 in Analytic Geometry for Shoaib

Question

Find the parametric equation of x=a(1+cos theta)

Answer 1

Here $x=a(1+cos \theta)$ is already in parametric form as $x =f(\theta)$

We can add $y=a(1-sin \theta)$ to make $y=f(\theta)$

Now, both $x$ and $y$ are functions of $\theta$ .
