    Undergrad When can one Change order of derivatives?

    Here is an example... d/dz(dp/dx) = d/dx(dp/dz) I don't remember learning this in my calculus or differential equations classes unless it was called something else.

    Weight before/after change in rotation Speed

    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?

    Undergrad Double Integrals Limits of Integration

    Hmm.. I see. Thanks a lot. With the functions that arise in double integrals, how to know if the function is even?

    Undergrad Double Integrals Limits of Integration

    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?

    Finding a relationship using 1st Law of Thermodynamics

    After posting this, I found something, why not divide both sides by T, that will give us the relationship the question wanted right?

    Difference between molar specific heat at constant volume and constant pressure

    This is a qualitative question not quantitative. But for some equations that do go with this are the following: Delta(E)=Q-W --First law of Thermodynamics
