1. The problem statement, all variables and given/known data
If the spacetime interval (delta S)^2 > 0, show that delta t=deltaS/c is the proper time between the two events. 2. Relevant equations Can anyone please explain to me how I should be approaching this problem. I have been working on it for a while with no success. I was able to do the problem before it easily, which was "use Lorentz' equations to prove that delta S is invariant", but this one is giving me trouble. 3. The attempt at a solution

I guess I worded the problem incorrectly. It should read "for ds^2 >0, show that tau=ds/c is the proper time".
