Here is an example...
d/dz(dp/dx) = d/dx(dp/dz)
I dont remember learning this in my calculus or differential equations classes unless it was called something else.
Yes, I understand that F=ma = 0 since the person will not move. Now the three terms that come into play... would the centrifugal force help at all since the earth is rotating?

I am just starting to do double integrals and came acorss an issue. I remembered from single integrals when we integrate from limits for say -1 to 1, we can double it and change integration limits to 0 to 1. Now, when is this the case? Basically, when can we not do this?
