Review Day!

We started off with some warm up questions that were labeled as "test rejects!". They were pretty tricky, so Mr. O'Brien made them worth extra credit. The first one ended up having the equation , and the graph looked like:











The second tricky graph had the equation and the graph looked like:



















These graphs were tricky, but they reminded us that we have to think about all math functions when taking the test, not just the six basic trig functions. After completing these graphing warm ups, we continued with our friend Francois as he kept biking around his neighborhood. We figured out numbers 21 and 22 in the packet, and made a few big connections, like how
= .

We then went over some homework questions and questions from past quizzes. We went over the conversions from angles to DºM'S'', which you find by multiplying the fraction of a degree by sixty, and if there is a decimal, by sixty again. We reviewed the "skiing down a mountain" problem from quiz three again, which is easily solved by using the inverse sine function. We also realized how important it is to make sure your calculator is in the right mode when solving problems (e.g. using degree mode on the ski hill problem). This is something to watch out for on the test!

We then took the review quiz, which only counted if we wanted it to! The quiz was made up of questions that had only been on previous quizzes, so if we had put some time into studying the quiz was a relatively easy grade. The quizzes were ready to be picked up by fourth period, so if we needed to, there would be time to review any of the quiz concepts we still had a hard time on.

The test is next class, and will cover all of chapter four. This is a ton of information, and I feel like it might be a little harder than some of the other tests because of all of the different functions. I'll really need to focus to remember things like how the graph of the cotangent is different from the graph of the inverse of the tangent. The homework for tonight is to choose a minimum of 8 review problems from pages 356-369. Mr. O'Brien left a warning on the iCal to not only do the easy problems. Especially in preparation for a test with on much information, it would be really beneficial to do some problems you have to think through. All unit homework must also be turned in before the test on Thursday, so make sure to organize it. Have fun studying!

The next scribe will be Hannah!
