A few things on section 12.5:
- This section is a bit tougher. It's going to take some practice be proficient at all the kinds of problems that show up. We'll go over some examples in class on Wed 27-Aug, and do several board problems. We'll also probably extend this lesson for an additional day.
- Check out the link http://www.dean.usma.edu/departments/math/people/peterson/geogebra/3dline.html. This visually takes you through the construction of a line in space. It's worth taking a look at this when you read over the first part of the section.
I was originally planning to have a quiz on Thursday. We will not have this quiz, but rather spend the time doing some more with lines & planes.
