Intermediate Algebra Assignment for 3/11

Your quiz on Unit 7 so far (Law of Sines and Sine formula for area) is tomorrow, Tuesday March 12.

After this quiz, we will move on to the next phase of the unit, a discussion of the Law of Cosines. Over the four-day weekend, I will want you to work on the Unit 7 Trigonometry Poster assignment.  Full information can be found at that link, and a preview of the rubric for the project can be found here (please note that this rubric is subject to change).

Intermediate Algebra Assignment for 3/7

More practice with the Ambiguous Case today! Remember: triangles where two sides and a non-included angle are given could actually refer to two different triangles, one unique triangle, or no valid triangles at all.

  • Homework: HW 7.6 – More Solving Ambiguous Cases
  • Lesson Video – Note that part of the “ambiguity” of the ambiguous case is that the same “SSA” set of information could determine 2, 1, or no triangles at all. We’ll have some more time to practice this in class.

Intermediate Algebra Assignment for 3/6

On Tuesday, we introduced the “Ambiguous Case” of the Law of Sines. Today, we spent some time working on how exactly one handles that situation.

One possible flaw with the Law of Sines is an issue of ambiguity that arises when trying to use it to find a missing angle measure.

We did an activity in class, so if you missed it you should watch the following short videos to see what it involved (they’re taken from another class that did the same activity): Setup, Partial Solution, Full Solution, Alternate Full Solution
