Help checking relativistic equations and LaTeX formatting

[IooqXpooI]

$$E=\frac{1}{2}W$$
^^^^^^^^^^^^^^^^
Note really sure about that one...

$$a=\frac{dt}{t_o \sqrt{1- \frac{v^2}{c^2}}$$
$$v=\sqrt{da}$$

Just to see how these fare with you guys(#2 is a play on the relativity equation), and how I'm doing with the 'tex' code.

Whats your point/question ??

Those equations don't make sense...energy and work are the same thing, E=1/2W is nonsense. v=sqrt(ad) doesn't make sense either. Relativity doesn't have distance and acceleration in it. I don't know what you did, but its definitely wrong.
