TIPS ON SUBMITTING HW ASSIGNMENTS WITH WEBASSIGN Please, never use your browser's BACK button in the middle of an WebAssign session. The system is designed to only move in the forward direction. The way things are set up at this time, you will have three opportunities to answer each part of each problem. To have your answer graded for a single part of a problem, fill in only that part and select "Submit New Answers to Question ____". If a part has been left blank, no submission is charged for that part. Always use three significant figures in your numerical answers (unless the program gives other instructions for a particular problem). Numerical answers must be correct to within 2%. NOTE: You can always easily tell the number of significant figures by thinking about the number written in scientific notation; the form *.**E** has 3 sig figs. Approximately 5 minutes after the due date for each assignment has passed, you will find a practice version of the assignment available. You may do this practice version as often as you like, but no credit will be given.
