I was thinking of how to represent this on a graph with (0,0) being the source of the wave. After some though I came up with:

y=x^2*y^2*t*(w-Vsin[theta])+x^2*y^2(Vsin[theta]-w)

t= time

w= speed of wave in the medium

v= velocity

[theta]= angle taken at right angle to motion counter clockwise.

This is probably wrong but I can't find it on google and got too bogged down to think it through again.

How did you work that equation?

How did you work that equation?

 

If by work you mean work out, I did it in my head.

If by work if you mean how does it work, I don't know if it does, I'll have to try it out on the software at school to see if it does anything right. Since I can't get there till next week that's why I posted here first.

You need to show the derivation really; we can't help without it.
