Homework Statement
Find the specific acoustic impedance for a standing wave p=Psin(kx)exp(jwt) where p is a complex variable.
Homework Equations
z = p/u (all variables are complex)
u = (A/rho_sub_0*c)*exp^(wt-kx)
The Attempt at a Solution
Approaching this problem it seems that I have all of the equations necessary. However when I divide P/u to find the specific acoustic impedance I get confused on how to handle the complex variables. I canceled the exp(jwt) and the P leaving z=rho_sub_0*c*sin(kx) although I am pretty sure that I broke some rules of complex numbers in that process. Can anyone clarify how to go about handling this division of complex terms. Also is A equivalent in this case to Psin(kx)?
