Focus your explanation on why you are doing a particular step, not on what mechanical process you used. Always use complete and proper mathematical notation. Avoid the misuse of symbols, especially the equal sign. The equal sign in mathematics states that the expressions on both sides of an equation represent the same thing. Always place units on your answers, and label all graphs completely and clearly, including scales and labels on axes.

The meaning may be clear to you, but it may not necessarily be clear to the reader. Define any symbol you use that was not introduced in the problem. If you use a graphing calculator in your solution, briefly explain your process and give the graphing window.
