So I'm flipping through the frames and I come to one where I was trying to explain how the slope of a vertical line is undefined, which I completely had forgotten about...
(Now with 100% less titlefail!)
A collection of lessons that I like from my class, or that I've found through the magic of the internets.
The poor guy's been hanging on there for a year now. How about throwing him a (horizontal) line?!ReplyDelete
He kind of reminds me of "Slope Dude". If you've never seen the Slope Dude video, let me explain: Slope Dude just loves to ski.ReplyDelete
As he makes his way uphill, he's puffing and panting, and it's a lot of hard work, so all the way uphill he keeps saying "Puff Puff Positive", until he finally reaches the top.
He starts sliding downhill, and he’s having a lot of fun. As he slides downhill, he says, "Niiiice Negative."
Then he comes to the boring part of the slope, which is just flat land. "This is zero fun," he says.
But Slope Dude isn't looking where he's going, so he falls off a cliff and yells out the worst swear word in the history of math: "UNDEFINED!!!"
This little guy is in a similar situation, except he’s skateboarding instead of skiing. :)
