I had a book for Excel version 2003 aimed strictly at engineering. It had a good deal of information on equations, notations, using the Excel "Solver" add-in and focused on functions that would be used more for engineering. It attempted to narrow the gap between Excel and programs like MatLab. I can't find the book anymore and figured there would have been an update for 2010.
