13.2 BrailleSense Math
This program allows you to create equations, or lists of equations, and perform
advanced graphing functions. Be aware, because this program needs to do
specific math related functions, it does break some of the usual interface rules.
When you first open it, you see an empty list, with the index 1/1. We use a list
view here for the purposes of being able to select math problems in the same
way you can select files or folders in a list, so that you can perform a single
action on all selected items. One difference though, because you will use Space
when writing math expressions, you will use Space-Enter to select the current
item.
To enter a math problem, simply begin typing. When you press Enter after
completing it, you will see an empty list item labeled 2/2. This will continue
happening as you enter subsequent math expressions and press enter.
As you enter math expressions, graphs are automatically created when you
press Enter, navigate away from the edit box, etc.
As you add expressions and graphs, they are added to the same image, the
same x and y axis, with each subsequent graph appearing in a different color. If
you graph more than 6 expressions, colors will be repeated, as there are only 6
different colors.
From the Word Processor, you can press Backspace-Enter-G to open the
graphing function, this automatically opens BrailleSense Math, and inserts the
current equation in to the list.
As with most other programs on BrailleSense, press F2 or Space-M to open the
menus. Menu functions are outlined below:
