Yesterday about 2/3 of my PreCalc class was taking the PSAT.
Today we will
practice some applications of Law of Sines and Law of Cosines.
You will not have
any homework tonight.
I do want to give you a headsup on what the quiz on Friday will look like.
You
can use the Law of Sines (ambiguous case) reference sheet
on the quiz.
Question 1:
Find the number of possible triangles
Question 2:
Solve a triangle using the Law of Sines (AAS, ASA, or SSA)
Question 3:
Solve a triangle using Law of Cosines (SSS or SAS)
Your Classwork today…
It is not your goal to go through these problems as fast as you can.
It is your goal
that everyone in your group knows how to solve these problems.
It is not
enough to be done.
I want everyone to understand these… thanks!
