May 12th Math Class a.k.a. 13 days until Kayla's birthday!!

First we started off having open revision time. We did problems, used Mr. O'B, and avoided second semester senior distractions :-).

Next we went over the HW Quiz. This showed that the ambiguous case is something we all may need to go over before the test. Know the rules for the ambiguous case and how to find values for b to make the triangle have a. one solution b. two solutions and c. no solution. In order to have a triangle the third side has to be between the sum and difference of the other two sides. For the example if a=9 and b=13 c has to be between 22 and 4.

The test covers: Chapter 5&6. Page 419 has a list of topics in chapter 5 that we need to know. We will be given sum/difference formulas, so no need to memorize. Section 5.5 all the bullets are on the test except for the second and the fourth bullet. It's a very doable test, just learn the basics. There aren't going to be that many finally crafted, so get the basics down. Page 481 tells what's on the test for chapter 6. 6.1Know the law of sines and area. 6.2 Know the law of cosines and the Heron's area formula. 6.3 know all. 6.4 know the dot product formula. Try to memorize all of the formulas but if not Mr. OB may help us. We will get the vector projection formula. We do not need to know the last bullet on 6.4 and 6.5 will not be on the test.

Last we finished up with doing problems and practicing our skills.

Remember study hard for the test on Monday. Put all of your homework together, corrected, marked, and in order.

Next scribe: Angus P.
