If the word " Integration " has not been mathematically explained to you in a calculus course, then think about this task as an estimation of "area under the curve". Everything is very simple when you think in terms of applications.

Spreadsheets ( a software for all walks of life ) are great tools for Engineering applications and / or presentations that are in forms of tables or graphs.

We will be using MS Excel, but if you have access to Quattro Pro you may want to try it. 
 Reading Assignments
We suggest that you use the help facility of excel as well as the material contained here. For numerical methods read Book1: Pages 420 - 429.
