This website shows how Excel can be used for engineering applications. Engineering students typically use software like MATLAB or MATHEMATICA during their studies in college but in the industry, most engineers only have Excel for crunching numbers. Excel is often seen as a business tool; but as this site shows, it is a powerful and versatile tool that can be used for a wide variety of engineering and numerical analysis.
Another objective of this site is to create an appreciation for the beauty of mathematics in general, and numerical analysis in particular. Mathematics is like art; it shows the power and beauty of the human imagination. It is very unfortunate that mathematics is often taught in a manner that creates dread in the students, but by showing how "difficult" mathematics can be done by simple operations in the rows and columns of a spreadsheet, it is hoped that at least a part of the fear will disappear. The "Engineering Mathematics" section on the Tools page shows how topics like algebra and calculus can be readliy understood with the aid of a spreadsheet.
