## Subsection3How to Use this Text

Because the text is free, any professor or student may use the electronic version of the text for no charge.

This text may be used as a stand-alone textbook for a standard first year brief calculus course focusing on economic and business applications without requiring knowledge of trigonometry. Chapters13 address the standard topics of differential functions; Chapter4 discusses basic integral calculus.

Calculus is not a *spectator sport*: understanding the topics requires reading the text, following examples in the text and in class lectures, and working on the problems in the text and on assigned homework. Learning comes from practicing the skills introduced and figuring out the solution. If you do not understand how to find a solution, consult with your instructor or ask for help so that when an exam is given, you know the process involved in solving the problems.
