The final exam is Saturday, December 12, from 7 pm - 10 pm in Sci 101.

Here are the solutions to the max/min problem worksheet from class. Here are the solutions to the related rates class worksheet. Here is a former 2nd exam, along with solutions.

**H****omework**** **

#1, due Wednesday, 9/2: Automathography, calculus contract, WeBWorK HW1, find my office (sign your name on the list on my door), diagnostic quiz (if you didn't finish it in class)

#2, due Friday, 9/4: WeBWorK HW2; Section 1.8: #1, 2, 3; these problems; start working on the pi-rate treasure hunt

#3, due Monday, 9/7:

You will need a calculator for this assignment! If you don't own one, there are plenty of good online calculators, including online graphing calculators (see link above). Remember: to solve a limit problem using "graphical" methods, you need to see a picture of the graph, so you'll need to use a graphing calculator to graph the function for you.WeBWorK HW3 (Note: for limits of functions with variables in the denominator, I highly recommend using graphical methods rather than numerical ones); from Section 1.8 of your textbook: #12, 13 (do both of 12 & 13 numerically), 26 (for this problem, estimate the answer to the first 5 decimal places--that is, keep plugging in numbers closer and closer to 0 until the 1st 5 decimal places of your output stop changing), 35, 50ab (be sure to set your calculator toradians!!); #41 from Chapter 1 Review; these problems; read this in preparation for Monday's lecture; the pi-rate treasure hunt is due Wednesday#4, due Wednesday, 9/9: WeBWorK HW 4; pi-rate treasure hunt; Section 1.8 -- #15, 54, 55, 56, 58, 60, 62; these problems. Note: the expectation is that you should solve every one of these problems algebraically--i.e., using one of the methods we talked about in class on Monday--rather than graphically or numerically. So no calculators will be necessary for this assignment.
