just another one of the random things that comes from sitting around with Arthur. He was griping about a math teacher he hated in high school. nearly failed her calc class because he wasn't using the exact method she wanted, though he was always coming up with the correct answers on his own.
I think he was trying to show me something with derivatives there.. or cosines.. and ... integers. So I've fallen into the trap of making a 'math comic', just like he does.
