Yes, we were talking with Alfy and when his Mom walked in with the camera, he quickly went to the video web site to throw her off. He was working a calculus problem and was stuck. We helped him out and he got it, but see if you can solve it. Its fairly easy as far as a Cavalier math problem goes, so it shouldn't take that long for someone as advanced as a human. Here it is:

Assume that

Show that f is differentiable at x=0, i.e., use the limit definition of the derivative to compute f'(0) .



We know, we know, its really simple and you don't want to see the entire solution. But Alfy was stuck on the very first step of the solution, so this is what Duncan was telling him when his Mom walked in:

The derivative at x=0 is

Got it. Easy huh? We are confident you know the rest but drop us a line if you get stuck.

I just talked to Construction Puppy and he said he will get right on it as soon as he is through with the installation of the linnear accellerator he is installing in his crate. He wants to do his own research rather than relying on the work of others. He said it should only be a day or two.

This is getting out of hand; do you have any idea what a full size crate that is large enough for his research costs?!
