# Converting parametric equations in a numerical equation

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"

"Numerical equation"? Can you given an example of what you mean? –  DonAntonio Oct 20 '12 at 22:42
@DonAntonio look at my answer, is it correct, right? –  FormlessCloud Oct 20 '12 at 22:46
Unclear question followed by an unclear solution. What can one say about it? –  Seyhmus Güngören Oct 21 '12 at 0:06
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. –  DonAntonio Oct 21 '12 at 2:44
@DonAntonio sorry, look at my updated question... –  FormlessCloud Oct 21 '12 at 13:24

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