Hello!
New to the hive here… working with my student. Trying out KeyMath, and Desmos calculator. Cannot seem to figure out how to simply plot points, and show them tactilely on the coordinate plane. He did space plus n, put in the coordinate points using appropriate nemeth code. Enter plus g, to graph nothing comes up.
Any help would be appreciated!!
Hi Patricia!
If you are plotting one point, this is a sample for how your braille should appear in Nemeth:
(open parenthesis, dropped 1, comma, space, dropped 2, close parenthesis)
If you are plotting multiple points, it should look something like this:
(open parenthesis, dropped 1, comma, space, dropped 2, close parenthesis, comma, space, open parenthesis, dropped 2, comma, space, dropped 3, close parenthesis, comma, space, open parenthesis, dropped 3, comma, space, dropped 4, close parenthesis)
Be sure that your boundaries are large enough to accommodate your points - for any coordinates with point values less than 10, use at least -10 left boundary, 10 right boundary, -10 bottom boundary, 10 top boundary. Add 10 to your boundaries each time your coordinates move into a new 10 (i.e., use boundaries of -20/20 for coordinates with point values of 11-20 and -30/30 for coordinates with point values of 21-30).
To set boundaries, press Space + Dots 3-5 while you are in the expressions list. Type a Nemeth negative sign (dots 3-6) for negative boundaries and UEB upper numbers (not Nemeth numbers). Press Space + E to return to the expressions list.
Just to let you know, the “dots” are enormous when they appear on the Monarch. They are only marginally functional right now. However, your student can get a sense of where they are located on the grid by doing one of two things:
Please let me know if everything works for you!
