May 1 Update

Medhnaa has to catch up with the content in her NOVA Social Studies class since the Final is due Sunday. She already has the essay topic for the final so I want to work with her over email or Google Docs to improve it. She plans to take the final Saturday morning, so that we can pivot toward the Precalc Final on May 5th.

Kushaan was finishing his NOVA Social Study final. Tomorrow he needs to write out a contract for how he plans to finish the SS Final paper which is about 9 paragraphs long. He also needs to complete the readings I gave him Monday for us to discuss a MIT OpenCourse class.

You can always see what I am posting for Kushaan and Medhnaa:

Motivation Writing

I shared some Expectancy-Value Theory research. The thing I need most from Kushaan is the outline of a 5-paragraph essay that will address the prompt (“Outline and then write a 5-paragraph essay of where you dream you will be at age 29.”). I also want to see the full writing but that may be too much to finish before we meet Saturday, but it should be done before school starts again Monday. There are also math problems about applying basic rules on his page.

Using Trig Formulas

This work goes back to slide rules and pre-calculator days. The idea is that all students have memorized many values on the unit circle, and there are 7 new rules they can use to find even more values. Teachers (and tests) do not expect students to memorize these rules, but they must be able to use them. The fail-proof way to solve all these questions is to:

  1. Write down the rule that will be used to solve the question.
  2. Calculate all sine and cosine values the rule needs.
  3. Put the values in the equation.
  4. Check the original question to verify whether the final answer is positive or negative.

All the rules needed in a standard trig class are listed in the graphic below. The unit on using formulas typically focuses on “Sum and Difference Formulas”, “Double Angle Formulas” and “Half Angle Formulas”.

Almost all questions look like straight calculation questions:

  1. Solve tan (-225°)
  2. Evaluate cos(\frac{5\pi}{12}
