We’ll use this page to keep track of what has happened each day in class. It won’t contain any of the nitty-gritty details, but will instead serve to summarize what has transpired each day.

**Monday, September 28:**We wrapped up Section 3.10: Related Rates.**Wednesday, September 30:**Today, we discussed approximations using tangent lines. This went quickly and then we did some more related rates stuff.**Thursday, October 1:**We spent the majority of the class meeting reviewing for the upcoming exam.**Friday, October 2:**The students took Part 1 of Exam 2.

**Monday, October 5:**We started discussing Section 4.2: Extreme Values.**Wednesday, October 7:**We continued with Section 4.2.**Thursday, October 8:**Zoom stopped working on us, so we threw in the towel.**Friday, October 9:**We got halfway through Section 4.3: The Mean Value Theorem and Monotonocity.

**Monday, October 12:**We wrapped up Section 4.3 and discussed the relationship between increasing/decreasing and the derivative.**Wednesday, October 14:**We discussed Section 4.4: The Shape of a Graph.**Thursday, October 15:**We got most of the way through Section 4.5: L'Hospital's Rule.**Friday, October 16:**After revisiting Problem 8 from Daily Homework 26, we tackled more examples of L'Hospital's Rule.

**Monday, October 19:**After cranking out one more example of L'Hospital's Rule, we started Section 4.7: Applied Optimization.**Wednesday, October 21:**We tinkered around with a couple more optimization problems.**Thursday, October 22:**We covered Section 5.3: The Indefinite Integral.**Friday, October 23:**We wrapped up Section 5.3 and discussed a couple problems on Weekly Homework 6.

**Monday, October 26:**We started discussing Sections 5.1 and 5.2.**Wednesday, October 28:**More discussion of Section 5.1 and 5.2.

Flagstaff and NAU sit at the base of the San Francisco Peaks, on homelands sacred to Native Americans throughout the region. The Peaks, which includes Humphreys Peak (12,633 feet), the highest point in Arizona, have religious significance to several Native American tribes. In particular, the Peaks form the Diné (Navajo) sacred mountain of the west, called Dook'o'oosłííd, which means "the summit that never melts". The Hopi name for the Peaks is Nuva'tukya'ovi, which translates to "place-of-snow-on-the-very-top". The land in the the area surrounding Flagstaff is the ancestral homeland of the Hopi, Ndee/Nnēē (Western Apache), Yavapai, A:shiwi (Zuni Pueblo), and Diné (Navajo). We honor their past, present, and future generations, who have lived here for millennia and will forever call this place home.
