Pressure variation of helium gas in equilibrium is given by $\triangle P=2.9x{ 10 }^{ -5 }cos(6.2x-3000t)$ where x and t have units m and s. What is the speed of the wave? This is a practice problem, I have the answer but no method on doing it. Honestly, have no idea how to start thinking about this. Any help?
