Need some help. I studied math a million years ago and my boss thinks I still remember anything about diff EQ besides my professor's haircut. I don't.
I have these diagrams (http://www.dubberly.com/stage/Maxwell2.jpg and attached).
I need to label them with appropriate formulas.
I have a whole pile of indecipherable stuff from a book "On Governors" about steam engine governors written by J. Clerk Maxwell in 1868. I know something in this pile is an appropriate label for the diagrams, but it would take me weeks to even hazard a guess.
I think that these diagrams have some canonical differential equation that's applicable. (Like y=1/x is one canonical formula for the Negative Feedback diagram, but it's not a differential equation.)
Does this make any sense? Can anyone help me with equations that would be appropriate for these diagrams? (I'm going to be showing it to some Stanford students, so it needs to be, you know, pretty accurate.)
Thanks so much in advance...
