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"

    @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

Solved:

$ y=h+\left(x\tan(\theta)-\frac{g}{2v_0\cos^2(\theta)}x^2\right) $
