what's the best way to make a formula/note sheet for a test? I recall Sidoh had made a formula formatting program, is that still online? Is there any software that will do this for you or am I best off with word or handwriting?
Sidoh's program used LaTeX so it may require you to learn some LaTeX-style syntax as well as do some extra work if you're referring to what I think you are.
But what I've used in the past, and is easier for what you want to do, is to use the Microsoft Word Equation Editor. If you have Word 2007, then the equation editor is pretty nice, easy to use, and to find. The Word 2003 equation editor is still pretty good and should work just as good for, but not as easy to get to.
If I remember correctly, you have to go to "Insert" --> "Object..." --> Scroll the list box and select "Microsoft Equation 3.0", make sure to check the box "Display as icon" before clicking the OK button so that every time you want to insert a new equation you can just click on a toolbar button.
