## Homework Statement

I have the trajectories of a particle in the space-time:

[tex]\tau[/tex]([tex]\sigma[/tex]) = [tex]\frac{1}{a}[/tex]senh([tex]\sigma[/tex])

x([tex]\sigma[/tex]) = [tex]\frac{1}{a}[/tex]cosh([tex]\sigma[/tex])

How can I write this equations depending on proper time t of the particle?
