Is it possible convert this parametric equations in a numerical equation?

$$ \begin{cases} \displaystyle x(t)=tv_0\cos(\theta)\\ \displaystyle y(t)=tv_0\sin(\theta)-\frac{1}{2}gt^2+h \end{cases} $$

Look at this Wikipedia's entry, at:

"Conversion from two parametric equations to a single equation"

    Unclear question followed by an unclear solution. What can one say about it?2012-10-21

    Answer...to what, @FormlessCloud?! You just wrote in your "answer" a mathematical expression which I've no idea what it is and what its relation with your question is.2012-10-21

    @FormlessCloud, I'm sorry to say this but your answer below *still* makes no sense. I know what is to try to make parametric equations into one single **equation**, but below you did NOT write any equation but only an expression!2012-10-21
