Yeah, agreed. Nonetheless, I've seen problems that have students create normal lines from normal vectors (which is easier, but still). Somebody once wanted it, it got added in to Stewart, and... here we are.

Nope, don't teach it. I agree that it's probably either (1) super-duper lookahead to Calc 3 / vector analysis (which nobody will remember and can be taught quickly anyhow) or (2) algebra review about slopes.

This beauty, munching on my winter carrots, will apparently become an Eastern Swallowtail.
I did not have the heart to move it. Fewer carrots for me, more for it.

This reminds me that I need to have my students translate "there's someone for everyone" into a properly quantified form. And then think about it reallllllly carefully.

I feel like "Students won't do assignments if I don't put points on them" is a whole separate post, maybe two, maybe an entirely new blog...

As in "aren't you just giving everyone an A then?" Or do they mean something else?

* I had to suffer through it, so should they (or, traditional grades worked for me).
