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...
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:

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...
