Intermediate Algebra Assignment for 3/19

Our test on Unit 7 will be on Friday, March 22, so we’ll spend tomorrow and Thursday reviewing the Law of Sines, Law of Cosines, and related information ahead of this test.

Tonight, please finish HW 7.10.

We did some more work with the Law of Cosines today, specifically looking at two cases where it is useful: when given two sides and a single angle between them (SAS) and when given three sides but no angles at all (SSS). Note that this second case is exactly what your poster will feature!

As we’ve observed in class, in order to use the Law of Sines, you must know (or be able to find easily) an opposite angle-side pair in the triangle. But what if all you have is two sides and an angle? Is there anything we can do with that? Enter the Law of Cosines, a generalization of the Pythagorean Theorem to non-right triangles.

Also, don’t forget about your poster project, due next Tuesday!

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).

We will have a quiz on what we’ve done from Unit 7 so far (Law of Sines and Sine formula for area) on Tuesday, March 12. For a visual summary of the various cases of the Ambiguous Case, watch this video.

We’ll spend some more time on Monday reviewing, but this weekend please finish the IXL assignment given in class. Complete the three IXL modules linked below to a score of at least an 80 on each. All three modules count as a separate homework credit, and any score above 80 will count as extra credit!

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.

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.

Another interesting use of the sine function in non-right triangles is in calculating the area of the triangle. The formula is simple, requiring only two sides of the triangle and the included angle.

As you’ve no doubt figured out, the project we’ve been doing in class is a review of Right Triangle Trigonometry, a topic you studied in depth in Geometry. The first part of this week is a formal review of the vocabulary and questions that you saw last year.

The last topic from this unit is an introduction to the concept of logarithms, which is a pretty big part of the full Algebra 2 curriculum, but not one that has a lot of focus for us in Intermediate Algebra.

Today’s lesson was about solving equations when the variable is in the exponent. The trick is to get both sides of the equation to be in terms of the same base, which is why having a good familiarity with various powers of bases 2-10 is so useful (and why I’ve been quizzing you on these daily).

We expanded on the use of rational exponents today, this time in the context of using them to solve equations.

A reminder: because I want you to be able to work through this chapter without relying on the calculator, we will have a daily Powers Quiz. I will choose 10 powers from the table you made on HW 5.1 and ask you to evaluate them without using the calculator in a brief, timed quiz. We will do this every day through the unit, and only  your highest grade on any one quiz will be the one used in your Unit 5 grade.

As we continue to explore the use of i to represent the square root of -1, and the consequences that such a definition involves, we revisited the topic of rationalizing today, and noted that since i is a square root, the rules of Simplest Radical Form require that we not leave i in the denominator of a fraction.

Our test on Unit 4 will be on Friday, January 18th. Please do not be absent on that day! If you know for some reason that you will be absent on that day, please arrange a time before the 18th to take the test! Otherwise, we will have to schedule a time for you to take the test during exam week.

More work with imaginary numbers today, in particular simplifying expressions that involve multiplying them or with higher powers. We saw in the videos we watched yesterday that powers of i don’t increase like other real numbers, but instead cycle through the numbers 1, i, -1, -i, and then back to 1 again.

First, a reminder of the homework protocol.

  • Homework is assigned every day and due the following day. Homework is assigned every day and due the following day.
  • Late assignments will be accepted ONE day late for half-credit.
  • If you are ABSENT FROM CLASS, you are expected to turn in the assignment you would have submitted on that day on the day that you return. You will be given one additional day per day of absence to turn in the assignments you missed.
    • For example: Goofus is present on Monday and absent on Tuesday. On Wednesday, he must turn in Monday’s homework, and he has until Thursday to turn in Tuesday’s assignment. He gets no extra time on Wednesday’s assignment; that is due Thursday also.
  • If you are having difficulty with an assignment, it is your responsibility to arrange extra help. We usually have time to discuss one or two topics in class, but if that’s not enough please come and see me!
  • New for 2019: Any student who has 3 or more unexcused missing assignments will be assigned a lunch or after school detention to make up the missing work. This work will or will not be accepted for credit based on my discretion!

Your quiz on the first part of Unit 4, all about rewriting radical expressions in Simplest Radical Form, is tomorrow. We made a study guide today, linked below, and got a review sheet that will be collected for homework tomorrow. The solutions are posted below as well.

Still more work with simplifying radical expressions today, now with expressions that include variable components. The method of dealing with these terms, fortunately, is fairly straightforward.

We will have a quiz on our work in this unit so far on Tuesday, January 8th.
