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:
// 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.
// But what’s really going to be on this quiz?
Honestly, this time it’s all going to be from Section 5.5.
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
