I am so confused with the cartesian equations. Why does it exist in the first place? Is it just to make me suffer!!!

WTF do we do if our HW problems are a billion times more complex than this?
If anyone can help me solve something like:
x=cos(5t), y=sin(2t) and get a Cartesian Equation out of it I would be EXTREMELY grateful!
