Follow-up to today's lesson

Since we did not have enough time in class to look at all the examples I had planned today, I have created a document that shows how to solve those problems.

2-8 Inverse Trig Functions

Here's the lesson from today for Yellowstone students.

Keep working on the homework!

2-8 Implicit Differentiation

Here's the lesson from today for Yellowstone students. Tomorrow we will develop differentiation rules for the inverse trig functions.

Quiz Next Tuesday (9/28)

Please keep working on the current homework assignments. The differentiation rules do take a lot of practice! As you have seen with class examples and in the homework, you'll need to combine rules together (for example, trig with product rule with chain rule). However, if you don't know the basic rules, you won't be able to handle the more difficult problems! The quiz next Tuesday is your opportunity to make sure you know the basic rules. I have updated the quiz to include the two versions of the limit definition of the derivative. Online you will find a copy of exactly what the quiz will look like and the answers. When you take this quiz next Tuesday, you will be given about 5 minutes to complete it.

2-7 Lesson

Here is the lesson from today for Yellowstone students (or anyone else absent). Sorry, the audio did not work well, but maybe you can follow along with the notes. I'm getting a new microphone tonight.

Grades

Please check your grades using Gradespeed. The test #1 curve has been added if you submitted completed test corrections. So many of you submitted reflective, thoughtful corrections. Nice work! After working with many of you this week during lunch and hearing your questions about the test, I decided to increase the curve SLIGHTLY. It is 2/5 of the points lost instead of 1/3 as announced last week. Also, the quiz today was completed well by most students (the mean was 90%). I was pleased with the discussions I heard during the group quiz - sharing your ideas about how to solve a problem is very important.

I will be issuing progress reports early next week. Some of you will need to make a decision about your commitment to this course. I truly want all of you to be successful in this class. Although it is difficult to determine an exact cut-off point, I would be especially concerned if your current average is < 80 and/or if your score on the first test with the curve is < 80. Remember the suggestions you read in the course guide ... have you been doing everything you can to succeed in this course?

• Pay close attention during class, ask questions, and share your ideas
• Leave class each day with detailed notes
• Avoid distractions during class such as studying for another course or sleeping
• Complete all assigned homework and get help with any problems you do not understand
• Begin reviewing days before each test
• Attend class regularly and arrive on-time

There will be about 130 additional points (including one quiz and one test) before the grading period ends on October 1.

Be sure to spend time completing the recent 2.3-2.5 homework. Please attend lunch tutorials early next week if you have any questions. Among other things, we will learn how to differentiate trig, inverse trig, exponential, and log functions next week. Enjoy the three day weekend!

2-5 Video

In most of my classes this morning, we did not have enough time to examine derivatives of inverse functions. Here's a link to a short video I made to help you with this. Remember that tomorrow your groups needs to be prepared to share solutions from 2.3-2.5 and there is a quiz covering 2.1-2.2.
