that are given in the WebAssign environment. The links below are to
public forms of the problem and may not include specialize WebAssign instructions.
You will be asked to do 3-5 challenging problems including estimations, explanations, essay questions, worked out problems, and even some challenging multiple choice questions. You are encouraged to work on these with friends. The course center is good space to work together and get feedback from a TA or Professor. CLICK FOR THE COURSE CENTER SCHEDULE. You have to write up your solutions independently. Be careful: If two or more submitted answers are essentially identical, neither will receive credit. In the "show your work" box in webassign, we ask you to explain your solutions. Solutions are to be written up nicely -- like a report. They can be expected to include equations, calculation, drawings, and graphs. The quality of the presentation will be considered in the score as well as the quality of the solution. Note that you can upload pdf or other documents. You may include clear handwritten information that is scanned in via scanners (available in the library) or smartphones. Homework is due by Friday 5pm for both sections of the class.
