Trochoid II

I can still do math. Last night before falling asleep, I solved that problem in my head.

I worked it out today on paper. May have Kaley help me type in the derivation.

Most stuff I do, I solve on the computer.

I have to think about solving "in my head", "on paper", "on the computer" and "experimental verification".

I struggled with formulating this... and had more to say but Kovi just came in with a cellphone popped open and said, "Remote control to spaceship!" We watched a single episode of Star Trek this evening and the boy is already a Trekky (which I never really was).

PS: I stole that art-like image of trochoids off the internet.

PPS: It just keeps rolling and rolling... like a snowball.
