What is this problem about?

Finding the unit tangent vector and principal normal unit vector of an <x,y> vector, at two different points. But the vector includes sine and cosine in it, which makes it extremely unwieldy, so I couldn't simplify down, and ended up with monster equations. Then when I evaluated at the points, both times the principal normal failed, once on divide by zero, and then next on imaginary number.

And I went down to work to find out why I hadn't been contacted, and because I really needed a break after all the calc.

I've always been skeptical of Brother printers, but for $99 for a color scanner, copier, and laser printer with both wired and wireless networking, I can risk it.

My computer closet is reaching catastrophic proportions. Every time I open the door, I'm afraid I might be killed by an avalanche.

Ah nice! I've the HL-2280DW

Seems really cool so far. I'm just glad to have a scanner and a printer that works well with Win 7. My LJ 4L worked fine on my old Windows 7 machine, but that was upgraded from Vista and used the Vista driver IIRC. It just seemed really buggy on a fresh load of Win 7. Too bad, as I love that little printer but I'll keep it for backup.

I;ve started. Going box by box. Listing things in FSFT as I go.

Most of mine is just going to the trash. There are a few things I can potentially sell, but most of the stuff won't sell for enough to make it worth my while. I bet I could fill a couple of 33 gallon trash bags without breaking a sweat.
