I’m writing this at 12 noon, and by the time most of you read this, the region meet will be over. Just wanted the runners to know I was praying for you today.
We went over the quiz on trig derivatives today. Remember to change the bottom number to 45. The major problems came as a result of incorrect simplifications. Don’t let the careless errors in algebra or trig bother you too much. You should be more concerned about misconceptions that are causing you to miss problems. Ask questions about those.
Some of you have mentioned the possible need for a “trig rehab” help class where we talk about things like sines, cosines, and tangents of angles like 3π/4 without a calculator. Please e-mail me if you would be interested. Mention specific topics that you would like discussed as well as a time of day/day of the week that is best for you. We could meet after school or during 5th period.
We began discussing Quick Review 3.4. (Hints were given in yesterday’s post.) You should make sure that you are familiar with all of the topics covered by that review in case we have a surprise quiz tomorrow. No homework was given
Tomorrow, we will finish section 3.4 on velocity and acceleration.
