# Making friends with the unit circle

Here’s a double sine/cosine animation showing how the unit circle definitions of sine and cosine determine the trigonometric graphs we know and love:

If today’s class left you thinking that you’d like a bit more background on the unit circle definitions of the trigonometric functions, try watching this Kahn academy video:

# “Possible” Homework Quiz on Monday

### // What is fair game for the quiz?

Everything since the last quiz (which was our 231 Review Quiz) is fair game for the quiz, which means anything in Sections 5.1–5.5.

Honestly, this time it’s all going to be from Section 5.5.

• According to the updated Calendar, Monday will be Problems Day, which means that there is a good chance that we will have a 10-point Homework Quiz on that day. Anything since the previous quiz is fair game for a Homework Quiz, which here means that anything from Chapter 5 could be on Monday’s quiz, if we have one.

# Wednesday 2/1 – out sick :(

Hello everyone, looks like the JMU bug caught up to me and I’ll be out sick on Wednesday, so there will be no class. Please note that this pushes our schedule around so that Section 5.5 will now be covered on Friday, and our next Problems Day (and potential Homework Quiz) will move to Monday.

### // What should I do now?

• Use the extra time between now and Friday to catch up on any homework problems or reading you may have missed
• Be ready for a Daily Quiz on Section 5.5 on Friday
• Be ready for possible Homework Quiz on Chapter 5 on Monday

# Monday 1/30 – Exponential Applications

### // Before class

• You should have done all the reviewing and final material needed to have mastery of Sections 5.1–5.3
• You should have read and taken notes on Section 5.4. If you have questions about anything in the reading then please enter them here so that we can discuss them at the start of class:

### // During class

• Daily Quiz on Section 5.4
• Questions? Nametags?
• Class discussion and group work on Section 5.4

### // After class

• Complete all homework for Section 5.4, as much as needed for you to feel that you have mastered the section. Since this section is primarily about applications, you should obviously do a lot more applications problems than the usual Homework Notebook guidelines suggest.
• Here’s a breakdown of what you might choose as a minimum homework set for Section 5.4, to be completed before Wednesday’s class:
• Thinking Back – all problems
• Concepts – #0, #1, #2, and at least five more from #3–18
• Skills – 3 problems from #19–24, and 4 from #25–37
• Applications – A variety of 15 problems from #38–51
• Proofs – For this section spend your proofs time on additional applications
• According to our trusty Calendar, you should also read and take notes on Section 5.5 before Wednesday’s class. Hooray, L’Hopital’s rule is coming!

# Friday 1/27 – Problems Day

### // Before class

• You should be done with all of the reading and homework from Sections 5.1–5.3, except for a list of questions that you need help on, despite already trying them and seeking help from study groups and/or the SMLC.

### // During class

• Daily Quiz (attendance only)
• Students ask questions about the reading, examples, and homework from Sections 5.1–5.3. When you ask a question, don’t say just “how do you do number 17?”; instead, describe how far you got on the problem and the point at which you got stuck.

### // After class

• Anything from Sections 5.1–5.3 that you still don’t understand? Still not sure about the 231 review material? Use this weekend to review and catch up. In particular, make sure that you have:
• completed the Review Packet
• re-taken the Double Homework Quiz, if you got below a C- (not for credit, just to make sure you have resolved any issues)
• completed at least the minimum amount of homework in each of Sections 5.1–5.3
• set up a Study Group and/or visited the Science and Math Learning Center, or both
• Read and take notes on Section 5.4 to be ready for Monday’s Daily Quiz

# Wednesday 1/25 – Exp and Log Derivs

### // Before class

• You should be done with all the homework from Section 5.2 and have read and taken notes on Section 5.3

### // During class

• Daily Quiz on Section 5.3
• Questions? Nametags?
• Discussion and group work for Section 5.3

### // After class

• Finish the reading/examples for Section 5.3 as soon as possible after class
• Do at least this minimum amount of homework for Section 5.3, before the next class:
• Thinking Back – all problems
• Concepts – #0, #1, #2, and at least five more from #3–16
• Skills – in general, recommend choosing a wide variety involving both exponential and logarithmic functions at various difficulty levels; choose at least 12 problems from #17–44, 2 from #45–48, 2 from #49–52, 2 from #53–56, 2 from #57–60, 3 from #61–68, 3 from #69–78, 3 from #79-84
• Applications – 1 from #85–#89 (#87 and #88 look particularly good)
• Proofs – 2 from #90–98 (best ones include #90–92 and #94)
• According to our Calendar, Friday will be a Problems Day; this means that you don’t have anything new to read before class. However, remember that we have four remaining Homework Quizzes, and they will each be given on Problems Days. This means that there is a chance that there could be a 10-point Homework Quiz during Friday’s class, so make sure you are all caught up on the homework from Sections 5.1–5.3.  In addition, bring a list of questions from those sections to ask about in class.
