Fetch, Boy! Fetch!

The story under the cut is, at best, mildly amusing. It is also completely pointless. The title may be the best thing about this post. You have been warned.

( Getting Some Exercise )

O Tempora!...

Currently, in my calculus class, I'm covering integration techniques. Now, there are techniques that are, so to speak, broad-spectrum, like substitution or integration by parts; they can be brought to bear in a wide variety of situations. But there are other techniques that are more restricted; some, in fact, that work in only one situation, or an extremely restricted set.

I was outlining one such technique today. (If you're curious, it's the one for integrating e^x sin x.) I pointed out that the trick used works only for the one situation. (Well, you can insert constant factors into various points, but it's really just the one.) Then I said, "You might say that it's a one-pony trick."

Pause.

Dead silence.

I turned around and gazed at them for a moment. "Have any of you ever heard the expression, 'one-trick pony'?"

Dead silence. Not one hand rose.

Ne-e-ever mind...
