I have a question about some Calc III notation and problems.

Question

cmonkeys · Answer

Specifically with number 2

inkyvoyd · Answer

just fyi you probably want to point out that that's a former test and it's for practice, so you don't get banned by some trigger happy mod.

cmonkeys · Answer

Oh is there a way to tag it. Its not the exam, its a practice exam.

cmonkeys · Answer

I already have a pdf of all the answer key, I just don't understand the notation

inkyvoyd · Answer

can you post the answer key? might make it easier for us all.

inkyvoyd · Answer

https://www.earth.ox.ac.uk/~larak/MMES/PartialDerivatives.pdf looks like it's just helping keep track of what other variables are kept constant.

inkyvoyd · Answer

make sense?

cmonkeys · Answer

I am reading what you posted, but I am getting lost. Haha

cmonkeys · Answer

I kind of understand what you sent, but I do not get how to apply it to the problems like on the practice test...

inkyvoyd · Answer

well just ignore it basically.

inkyvoyd · Answer

Then readd it at the end. THe subscript variable is entirely unnecessary, and the only thing it does it says that i'm keeping this variable constant

cmonkeys · Answer

AHHH it all just clicked, Thank you so much I get it now
