*Here are some Mathematica tips… reply with your own, or email me, and I'll award some bonus points!*

## The Three Most Common Errors

- Did you use square brackets for functions?
- Did you
**capitalize**function names?- Example: use "
`Cos[t]`", not "`cos[t]`" or "`Cos(t)`" or "`Cos t`" - If its blue, Mathematica will treat it as a variable

- Example: use "
- Do you have spaces or "
`*`" whenever you multiply two variables?- Example: "
`xy`" is the variable named "xy" whereas "`x y`" and "`x*y`" represent the product of "`x`" and "`y`".

- Example: "

## Brackets, Braces, etc.

- Use
**parentheses**for*order of operations*, e.g. "`(1+x)^2`" - Use
**square brackets**for*functions*, e.g. "`Plot3D[ ]`" or "`Sin[t]`" - Use
**curly braces**for*vectors*, e.g. "`{3,4,5}`" represents the vector $\langle3,4,5\rangle$ - Use
**curly braces**for*lists*also, e.g. defining plot parameters as "`{t,-5,5}`"

## Section Titles and Cell Formatting

Use formatting commands to add in section headings, problem statements, and notes to your workbooks. The easiest way to do this is to highlight a cell (click on the bracket on the righthand side of the window) and then hit Alt+1, Alt+2, etc. I cycle through these until I find what I want.
