We are getting very close to the end of all new content for the year!

Dates: Quiz over unit circle degrees, radians, and coordinates (6 sketches given, questions are just like the last test), Tues-Wed, May 8-9 - 24 pts.

Big Quiz over volume and 3-dimensional geometry - May 15-16, 40-50 pts.

Finals over spring semester content - May 21-24, 20% of semester grade.

Today in class we learned three things:

We went over HW #12 in detail to make sure everyone has a chance to master the content. (mostly volume of pyramids and cones).

1st period learned about 2-d figures formed when a solid is sliced by a plane.

There was quite a bit of time in class to practice while students were able to (finally) view their tests. Those will posted Tuesday, along with adjustments to the last quiz.

In class practice: p 84:18-21, p 526: 16-18.

HW #13 - p 532:3-5,7,10-11, p 536:1-4, p 543:1-6.

Today in class we learned three things:

- how to interpret a solid of revolution (what 3-dimensional figure forms when this 2-D figure spins around an axis?) and find its volume;
- formula for volume of a sphere = 4/3 time pi times r^3; hemisphere is 2/3 not 4/3. p 542
- irregular volume: an irregular solid placed in a tank of water will displace its volume. There are a few density problems associated with this (p 535)
