SUMMARY

The discussion centers on deriving the parameter β related to superluminal motion, specifically using the equation β = v/c = 1/(cos(θ) + sin(θ)). The user also inquired about plotting β as a function of θ to identify regions of superluminal motion. The original poster, Max.Planck, later resolved the problem independently and offered to share the solution privately.

Hi,

I have a question about a problem on superluminal motion. Using the following figure (see attachment) I have to derive that:

a) \beta = \frac{v}{c} = \frac{1}{cos(\theta)+sin(\theta)}

b) Plot \beta as a function of \theta and show where the superluminal motion takes place

Thanks!
