Best ResponseYou've already chosen the best response.0try the physics section! but from what i recall.... this is a standard sinusoidal wave function where the generic version looks like D(x)=Acos(wt+phase shift) or something close to it..... so the amplitude would be 3... and the phase shift would be 3pi/2.... but check and make sure that D(x) equation is exactly correct... bc its been awhile haha
