#1, due Wednesday, 9/3: Automathography, calculus contract, WeBWorK HW1, find my office and Kaitlyn Litwinetz's office (sign your name on the lists on our respective doors), diagnostic quiz (if you didn't finish it in class)

#2, due Friday, 9/5: WeBWorK HW2; Section 1.8, #1, 2, 3; these problems

#3, due Monday, 9/8:

Note: for the textbook problems, you may use either numerical or graphical methods to find the limits. Either way,

- WeBWorK HW3; AND
- from Section 1.8 of your textbook: #10, 14, 30, 31, 51ab (be sure to set your calculator to
radians!!); AND- these problems; AND
- read this in preparation for Monday's lecture; AND
- this field trip (this part of the assignment is actually due Thursday at 10pm)
you will need a calculator for this assignment! If you don't own one, there are plenty of good (free) online calculators, even online graphing calculators. Remember: to solve a limit problem using "graphical" methods, you need to see a picture of the graph, so you'll need to find something (or someone!) to graph the function for you.#4, due Wednesday, 9/10:

- WeBWorK HW4; AND
- Section 1.8: #15, 54, 55, 56, 58, 60, 62; AND
- these problems; AND
- this (if you haven't already done it; actually due Thursday at 10 pm)
Note: the expectation is that you are able to do every one of these problems algebraically--ie, without a calculator, using the methods we talked about in class on Monday--rather than graphically (ie, by plotting a graph) or numerically (ie, by creating a table of values).

#5, due Friday, 9/12:

- WeBWorK HW5; AND
- Section 1.7: #3, 4, 11, 12, 15, 16, 19, 20, 22, 30ab; (for #11, 12 use the IVT)
- (if it's not after Thursday, 10 pm, you still have time do this)
#6, due Monday, 9/15:

- WeBWorK HW6; AND
- Section 2.1: #1, 2, 4, 7, 18, 19, 20, 21, 27, 36
#7, due Wednesday, 9/17: WeBWorK HW7; AND Section 2.2: 1, 4, 10, 11, 12, 13, 14, 15, 17, 18, 20, 41, 43, 45, 47
