The WebWork course for this class is called  math20b-coordinated-wi15

All assignments are due at 5:00 A.M. to avoid heavy server traffic. Solutions to homework assignments will be made available in WebWork after the 5:00 A.M. deadline on the specified due date. Solutions (as well as the exercises) are generously provided by W.H. Freeman and Company (the publisher of our textbook). Some errors may result from randomness. If you encounter an error with WebWork, report it in Piazza.

The following is a list of accepted WebWork functions.   (This list is taken from the MAA List of Available Functions.)

Mathematical Symbols Available In WeBWorK

+ Addition
- Subtraction
* Multiplication can also be indicated by a space or juxtaposition, e.g. 2x, 2 x or 2*x, also 2(3+4).
/ Division
^ or **       You can use either ^ or ** for exponentiation, e.g. 3^2 or 3**2
( and ) You can also use square brackets, [ ], and braces, { }, for grouping, e.g. [1+2]/[3(4+5)]

WeBWorK is case sensitive. Do NOT write "X" when you really intend "x".
