InCA Lesson 6.4 – Law of Sines Part 2 – Ambiguous Case

As you are aware by now, schools have been shut down for the remainder of the school year. This means that we will be continuing with this distance learning model until June. I don’t currently know exactly when the last date of instruction will be, but will be sure to let you know as soon as I find out.

I am shifting our schedule slightly for the remainder of the academic year. The first part of our lesson will be posted on Tuesday, with the video and Problem Set 1 due on Friday. The Desmos assignment and Problem Set 2 will be due the following Tuesday. Full details of the new schedule are here.

PROBLEM SET 2 for this week can be found here (as a Google Form) or here (as a PDF download). Submit your answers to this and to your Desmos activity by Tuesday, 5/12 at 2:00 pm. You must obtain a target score of 4 out of 6 points to earn credit for this assignment, but your grade will not be based on how many points you get (just whether or not you made that cutoff). If you submit via the Google Form, the form will tell you which answers were right or wrong, however once you finish the problem set, I will need to access your responses and evaluate for explanations to finalize your score.

Reaching the target score on this assignment worth 8 points in SchoolTool. Submitting the work but not reaching the target score is worth 6 points.
