What the reader sees in print is a reflection on you. Organize your work in a logical way. Do not crowd your work. Leave some room for corrections and comments. All of your homework must be word processed, using an equation editor for mathematical symbols.
Most problems contain many quantities.
Define any symbol you use that is not introduced in the problem. Always use complete and proper mathematical notation. This is extremely important. Avoid the misuse of symbols, especially the equal sign. The equal sign states that the expressions on both sides of an equation represent the same thing.
