1-2-3 for scientists and engineers is a sourcebook of numerical methods, explained in detail and implemented on the Lotus 1-2-3 spreadsheet. More than just a simple "how-to" guide, this book shows that spreadsheets are particularly well suited for solving the numerical problems commonly encountered in science and engineering. Through scores of examples based on real scientific applications, the author shows step-by-step how to obtain solutions quickly and elegantly, and present the results in an intuitive, graphic format.
