Hello Andy Resnick. That is what I also tought at first, but the fact is that these terms are not the classical preassure terms. And I still have not been able to find a physical explanation for them. Could one say that since the fluid has viscosity, we will have a "glue-effect", so that...

Hey!, I was repeating for myself a course I had from a earlier year, fluid mechanics. I looked at the derivation of the navier stokes equations, and there is one term that does not give meaning to me. Take a look at the x-momentum equation here...

From my Linear Algebra course I learned tha and eigenvalue w is an eigenvalue if it is a sollution to the system: Ax=wx, where A= square matrix, w= eigenvalue, x= eigenvector. We solved the system by setting det(A-I*w)=0, I=identity matrix Now in an advanced course I have come upon the...

Sorry I meant about the x-z plane not object symmetric about the z-axis. Is it still valid then? Thanks for your reply!

Hey, this is actually a question arising from physics, but it is actually only mathematical. Let's say you have a 3 dimensional object, with the origin in the volume-center. -the object is symmetric about the x-z axis -If we look at slices in the x-y-plane(z=constant). Will then the...

Hi, I am supposed to find the point on the cone z^2=x^2+y^2 which is closest to the point(9,12,5). here is my work: http://img27.imageshack.us/my.php?image=lagrange001.jpg Is it correct so far? If it is: I get stuck when trying to solve the equations z^2=x^2+y^2, x=9/12*y, and...
