Waveequation for relativistic particle

How do I find the wave equation for a relativistic particle from E and p in terms of their operator-equations, $$E \leftrightarrow$$ $$i \hbar$$ $$\frac{d}{dt}$$ and $$p \leftrightarrow$$ $$- i \hbar$$ $$\frac{d}{dx}$$ ?

I'm assuming I'll have to use: $$E^{2}=p^{2}c^{2}+\left(m_{0}c^{2}\right)^{2}$$
and substitude the operator-equations into that, but where to go from there? i'm lost.

Thanks heaps

What happens when you do that substitution? Because that's all that there is to it...

haha, yes i realized that, I was trying to get the wave function instead of the wave equation, and thats why it was a bit hard to do like that in my head.

Thanks though :)

This is basically what you're trying to get at, right? Note that this isn't the relativistic wave equation used in QFT - that's the dirac equation - since this equation doesn't incorporate spin.
