# Problem on superluminal motion

#### Max.Planck

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!
