Deriving parametric equations

    I've recently attempted the following problem,


    with the following solution


    I've managed to form the meaningful derivatives (as they have listed on the solutions page) through a graphical analysis, but have no idea how they came up with the last two parametric equations. I wasn't even familiar with the term, and am getting myself up to date-any useful references...texts, internet site, specifically for this subject would be appreciated.

    I would appreciate any comments regarding how they have derived the last two parametric equations on the solutions page, though it seems that the equation might have been computer derived.

    It appears that they solved the system of DE's that they derived and plugged in the initial values. I only spent a few minutes on it, but unless there's some "special trick" they used to solve it, I'd imagine that they did in fact use a computer program.
