Homework Assignments

Homework assignments are to be emailed to the instructor usually in spreadsheet (Excel) format. The following rules must be followed:
  • There is to be a summary page with all answers in the order & units requested. Values in the summary are not to be copied by values but rather linked to any additional pages where the calculations are actually performed.
  • All spreadsheets are to be self contained, i.e., there are to be no links to other spreadsheets.

A sample spreadsheet with the preferred format is here.
