12-16

The objective for today's class was to first review the quiz we took on Monday. After that we started our next unit. This unit is about using trigonometric functions on right triangles. This unit is likely going to be a review of what you may have learned in a math class. However we will be using drawn vectors to create these triangles. We picked up pages 21 and 22 before class. Page 21 had some notes on it and examples on how to use the trig functions. There was also a small section on the Pythagorean Theorem. This theorem states that the hypotenuse squared, is equal to one side squared + the other side squared.Then on the back, page 22, has a table of each trig function for angles up to 90 degrees. This table is very convenient because you do not need plug the actual trig function into your calculator. Then, Mr. Manning passed out page 23 which had some practice problems on it. The remaining 15 minutes or so was given to us as time to work on the example problems. It seemed like the majority of the class finished in class so it did not take very long to complete. There was no daily question today, most likely because we had just taken a test and because Mr. Mannin wanted us to have time to work on the practice problems in class.
