Hi Dan and all,
This will be Chapter 8 in the finished book, but right now, for convenience, it says its chapter four.
I did a lot of copy-editing, error corrections, some reorganization, shortening of titles and captions and general cleanup. I moved and consolidated all the learning objectives to the beginning, and I added some new illustrations, one of my handouts about the procedure for the graphical method and another ggb applet. There is still plenty more that could be added improved, but so-far, so-good.
The material sort of peters out towards the end so there’s some more work needed there.
If you see errors, the best thing to do right now is probably to just send me a screenshot, or copy the existing paragraph and send me your revision.
Will
