Fundamentals of Physical Acoustics by David T. Blackstock. Any good physical acoustics book will explain wave propagation in various media.

So does this often extend to the kinds of jobs engineers have with an MS than simply a BS? As in posts earlier described that many engineers do not use much of their more theoretical knowledge in the workplace.

Hi, I've just been reading this whole thread. Very good points overall. Does anyone care to weigh in an opinion if this type of mindset among professors/engineering students is more common in an undergraduate curriculum versus graduate? I would think graduate programs have a higher maturity...

That example is just the non homogeneous term, so extend the example to something like y''+9y'+4y=3e^(-2t)(sint)

Hello, I had a question about the method of undetermined coefficients for solving ODE's. I understand it is only useful for certain non-homogeneous functions, and those dictate specific guesses, but what if I had a sum or product of two valid functions, is the guess simply a sum or product of...
