Day 56 in MAT229

Today:

• Announcements:
  • Last week! We'll be doing one more product (the cross-product), talking about how to construct linear objects and spheres in 3-space, and talking about some 3D motion. Then that's it.

  • HW 10 is due Thursday.

  • In a week (next Monday) you'll have your "recent stuff" portion of the final. It will be written like an "hour exam", but you will have two hours to do it. So you should have plenty of time.

    You may use your favorite calculator, and a one-page cheat sheet.

  • Then, on to the "final final", on Thursday -- the comprehensive part (covering old stuff). That, too, will be like an hour exam. If you do better on this one than on your lowest midterm hourly exam, this grade will replace that one.

• Today:
  • Let's wrap up Sect. 12.3: Dot product (pdf, pdf summary)

  • Then it's on to Sect. 12.4: Cross product (pdf, pdf summary).
