How do I find the equation in terms of x and y given a position vector and velocity vector? Given VectorPosition = (something1)i + (something2)j then x = something1, and y=something2. Remember, even if the position vector has some T^2 values in there, it could easily be linear. This is sort of like parametric equations. Vectors are easier to think of than parametrics, so that's why we teach them before. In precal, you're taught parametric equations, and you are never taught to relate vectors and parametrics together.
