Today was our Right Triangle Trigonometry Day in Geometry. We started with a warm-up that used 30-60-90 relationships to lead to the ideas behind Right Triangle Trig. The lesson is on pp 655-659 in the textbook. Please read through this material and examples to help you understand if you were not here. It is actually quite good and we used part of it in class today.
I recommend getting together with a friend who was here to work on the the homework #11: p 588:1-20,22.
On problems 1-7, 11-14 just use calculator. They are equations to solve that are like the "end" of the problems that you have in your notes. In other words, do I multiply, divide, or use the inverse to find an angle. On problems 8-10, do not use the calculator; just write ratios. On problems 15-20,22, use the examples from class and the examples from the textbook.
I am not sure if I will be here tomorrow, Feb 13. I am planning to return the quizzes tomorrow.
I had planned to give a quiz on Thurs-Fri over distance formula and equation of a circle. Since it looks like I may not be here, that quiz will not happen. You will have a short warm-up over that.
If you have not taken your quiz yet, Friday during A&E is your last chance.
On Thurs-Fri block, we will be working on using trig in real world problem solving, developing mastery of content.
Will post example notes below. Remember to read the book; it is helpful.
