When you are lying down and using a notebook/pencil is not easy, I could draw eqn's in a paint program, but I'm not good at that, especially lying down with a mouse on my chest.
So I was wondering is there some program, meant for people writing eqn's , to put as a picture in a presentation, or on a form. So in the program, there would be toolbars, and instead of placing circles, or resistors, you choose some math symbol or number/letter, and place it on the work space.
And I don't care if the program actually does math, I just want something else besides trying to draw eqn's in paint, when lying down. Maybe it would be really slow and not worth it. But I would put a circuit together in a sim, rather than draw it on paper or in paint, so I'd try a symbolic math editor/notepad
