In the old days, back in Calculus I, we called this the chain rule.

We don't know much about f, so just go with f'. That should do it. - Jun 19th 2011, 06:43 AMHallsofIvyRe: Partial Derivatives
Well, since this is not Calculus I, those should be partial derivatives: If we let ,

Yes, you can write "df/du" as just f '. - Jun 19th 2011, 03:46 PMTKHunnyRe: Partial Derivatives
I think I've never coded a "partial" in LaTeX. That's weird. I wonder how I managed to miss that...

Okay, I think I have it, now.
