It's difficult to read scanned images like this. Next time, please just make the effort to type out the relavant information yourself.

Anyways, are you referring to the equation, [tex]\mathcal{E}^2(1-V^2\cos^2\theta)-2\mathcal{E}\mathcal{E}_0\sqrt{1-V^2}+\mathcal{E}_0^2(1-V^2)+V^2m^2\cos^2\theta=0[/itex] ?<br /> <br /> If so, just use the quadratic formula and <b>post your work</b> if you get stuck.[/tex]
