As they evolve, so does my teaching.<br /><br />But, there are some topics that, no matter how great they're taught, the best teacher is lots of exposure to them and lots of practice. I think that goes for the chain rule. Yes, I do feel like I explained it better this time around, but, ultimately, the kids need to practice and figure out their own potential stumbling blocks.Rebecka Petersonhttps://www.blogger.com/profile/12227797437296056645noreply@blogger.comtag:blogger.com,1999:blog-7806043650549721218.post-53171222160929220782013-10-31T21:52:56.209-05:002013-10-31T21:52:56.209-05:00Rebecka, you are a sweetie.

I've never done that (keeping the inside the same). <br /><br />I always get them to describe the function using the word "something". y=six(3x) becomes y=sin(something). Then the derivative is y'=cos(the same something)*(derivative of the something).<br /><br />It wasn't good enough. Half my class forgot their chain rule on y=sin(3x)/x^2. They were busy using the quotient rule, and didn't even see the layers on that onion!Sue VanHattumhttps://www.blogger.com/profile/10237941346154683902noreply@blogger.comtag:blogger.com,1999:blog-7806043650549721218.post-15928738795105689522013-10-31T17:46:24.977-05:002013-10-31T17:46:24.977-05:00Awwwwwww, the same goes to you, so we're even!...Awwwwwww, the same goes to you, so we're even!Sameerhttps://www.blogger.com/profile/10743884978903636387noreply@blogger.com
