What Nancy is Up To

[Tanner]

Nancy sent me a email today about a problem on her PSET (no idea what that is) that was about robotics. She was happy. But look at the math!

The only thing I understood was the little section about derivatives and integrals in part B, and v(t). We're starting integrals tomorrow so I might get this one a little bit better after a few weeks.

Although something that's puzzling me is what is "K" in the PID equation?

Note to self: Get Sunny to teach Tanner integrals before Physics C.

Those are all constants. PID is simple to understand what it does, though figuring out more than that gets confusing with large math equations! Exciting! Its actually quite neat when it is working.

See these videos when I had PID working on Longshot's forks:

You've gotta go and get you one o' them TI-89s. Those calcs. make all math instantly 100x easier.

Hehe. I've played with a friends a bit, well not played so much as get lost and add my name to the Contacts list - seriously, why does a calculator need a contacts list? How many times do we get into the situation: "Oh no, my phone batter died - whatever shall I do? Oh wait, I've got my calculator."

It'd be interesting to sit with one for a while, but I bet there are darn expensive.

Edit: Expensive is a good word. A little over $300. Some calculator.

? I think you're looking at the wrong calculator. TI - 89s run about $150.

Hmm. Odd, whatever I found was a expensive calculator though!
