HERE, we present several commonly used mathematical formulas, the majority of which will be needed in this text. Although the reader should already have encountered these relationships in first- and second-year college mathematics courses, we believe that it is helpful to summarize them in one location.

In Table A.1, *r* is the radius of an object, *D* is its diameter, and *L* is the length of the cylinder.

Additionally, the area of a triangle of base *B* and altitude *H* is *A* = *BH*/2; and the area of a rectangle of breadth *B* and width *W* is *A* = *BW*.
