Answer:-
To find a Cartesian equation from parametric equations, start by identifying the parametric equations, usually given as ???? = ???? ( ???? ) x=f(t) and ???? = ???? ( ???? ) y=g(t). Your goal is to eliminate the parameter ???? t. Solve one of the equations for ???? t, then substitute that expression into the other equation. This gives you a direct relationship between ???? x and ???? y, which is your Cartesian equation. Be careful with domain restrictions and ensure your final equation is simplified. Sometimes, the result may not be a function but a relation like a circle or ellipse.
