Relativistic equations, how does one isolate variables?

AI Thread Summary
The discussion centers on the challenges of solving certain equations that seem resistant to standard algebraic methods, leading to questions about the necessity of numerical techniques. One participant suggests that normal algebra can indeed be effective, particularly if the variable in question is v, which is involved in a reciprocal square root. A request is made for an example to clarify the issue further. The original poster later admits to an error in their formula, which contributed to their confusion. This highlights the importance of accurately formulating equations when seeking solutions.

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

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.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
