The equation in my book is ridiculously long. They actually split it into 3 equations.

I can't tell you much as far as mechanical goes but it is very hard to find an aero/astro job right now unless you have experience, or live on the east or west coast. If you stick with aero get an intership or co-op. I graduated in dec '07 with a bs in astro from Purdue and I still can't find a...

At freestream M=2 will the red dashed shock exist? I know there is a shock wave on the bottom.

First I will admitt it has been a while since I have done image analysis with Matlab but what I think you are asking for is something like this. I'm not familiar with the double command so I'll just assume it is used correctly. Oh and don't use image as an imput and image is a command in matlab...

My experience with Fourier series is extremely limited and your hint doesn't mean anything to me.

I have the equation del^2 phi =1 for 2-d (x and y) with the boundary condition being 0 along all 4 edges. I've looked in all my math books and can't find how to solve this. If anyone could get me started I would appreciate it.

Thank you so very much for the help. I first found the complementary solution then add it to the particular solution and I am now solving for the constants. It's all starting to come back to me. It's been a handful of years since I took diff eq.

I can't seem to find anywhere how to find the exact solution to the equation when the non-homogeneous part is just 1 and not a function. I would very much appreciate it if anyone could give me some assistance. Also for the bounday counditions doesn't one of them need to be phi prime? Thanks.
