Find the cartesian equation.
I don't get what one is.
The answer is .
thanks!
is not a cartesian equation. It's not even an equation..
As far as I know, cartesian equations are equations that describe the curve using x and y coordinates, not parameters like .
You can see that .
If you can't see the relation between x and y (parametric equations are not always simple like this), you can do it algebraically.
