HW: Finish the handout problems 1-8 on the law of sines.

Your chapter text has been moved to next Thursday. STUDY and be ready for it.

TODAY: The Law of Sines.

The formula allows you to solve for triangles that are not RIGHT triangles. Solving for triangles means you must find all 3 side lengths and all 3 angle measures. Each measure will not require that you use the law of sines, but you will use it at least once. In some problems, you will use the Angle-Sum Theorem (the angle sum of a triangle is 180 degrees).

sinA/a = sinB/b = sinC/c

YOU NEED A CALCULATOR!!!!!!!!!!!!! PREFERABLY A SCIENTIFIC CALC. (at least), but a standard one will do too. You want the SIN, COS, TAN functions on your calc., if possible.

Check Amazon, Ebay, Craig's List, etc... a student found a TI-Inspire graphing calculator (worth $135, new) for $8!!!!!!! this way!!!!

About Tania Lopez Hipple

I love math!!! By the way, I had a baby May 26, 2010 (William, little Will) and he is doing great! This is my 9th year teaching math and my 2nd year at TPA. I have been teaching geometry at least twice a day since 2004 so it is a math subject I know inside and out!

In 2000, I received my B.S. from UCLA for Applied Math and a minor in French. I love languages. I'm fluent in Spanish too. I was born in El Salvador and have lived in Los Angeles since 1981, when I was 5...are you doing some math yet? I was always good at math, so this definitely helped my interest in the subject. I actually applied to colleges as a math major because I couldn't think of another subject I could dedicate a few years to and not be bored! I had no idea I was going to be a teacher until 2001. I got a job teaching 8th grade algebra and was suddenly thrown into the world of the Los Angeles Unified School District. After 2 years, it hit me like a ton of bricks! I love teaching. I want to teach math forever! So the following year I earned my teaching credential and a masters in Multicultural Education from National University. It's now 2004 and I finally got to teach at the high school level. I worked at Birmingham High school until the day I literally got into my car and drove to Tempe- the Friday of the last day of the Fall semester this year, February 6, 2009.
