You're correct, Huw. I'm currently taking a course in Control Systems,
and have recently finished courses in Advanced Circuits, Diff Eq, and
way too much calculus. The second derivative of x wrt time is, in fact,
d^2x/dt^2. If x represents position, the first derivative is
velocity, and the second derivative is acceleration.
ObAudi: I've been putting lots and lots of audio in my 90q recently.
The 90 has a tiny trunk, but I've found places for five power amps,
and an 8" woofer where the ski sack used to be. This weekend's
project: a 1.5 farad capacitor across the amp power leads!
