Relativistic equations, how does one isolate variables?

[Matt Jacques]

It appears that these equations are defying regular algebraic techniques, must their variables be solved by numerical techniques?

[Tom Mattson]

I've never run across a problem. Which variable(s) are you trying to solve for?

My guess is that you are trying to solve for v, which is buried in a reciprocal square root. If that's the case, then I assure you that normal algebra does indeed work.

How about posting an example of what you are talking about?

edit: Added the word "never" to the first sentence. Makes a lot more sense now!

Ooops, I wrote the formula down wrong, that explains why it didnt work out. Looks away embarrassingly.
