[BlindMath] I need some ideas and encouragement for doingbraillecalculus

Fri Sep 20 00:54:04 UTC 2019

Awe, Emily!
I am glad to hear that.
I had to be very creative, because I went to a regular public school where no blind person had attended.
I did use the Perkins Brailler a lot for matrices in Linear Algebra!
All of the operations you have to do with all of the rows and columns to simplify them, definitely took the Perkins to do that with!
You are right, tough, the more you can strengthen your ability to do math in your head, it becomes more time-saving, and easier than writing every step out in Braille.
I loved math when I was a kid, and I have always had just light perception, but no reading vision!
I can explain implicit differentiation to you in a way that will make it so much easier!
Remember that Y stands for an entire unknown function! That is why you put DY/DX after 2Y, for example.
That was very hard to do in my head as well LOL!
I would love to tutor you a bit around 4 or 5:00 PM Eastern standard time!
You can email me off list at:
Jesusloves1966 at gmail.com
I love to help people with math more than doing math LOL!
I tutor a lot as a side business!
I look forward to hearing from you, and keeping in touch!

Hi. You have really inspired me, and now that you mention it, I am much calmer when I’m doing math mentally. The problem is, it is hard for me to keep track of problems where I do three or 4 chain  rules and one or two product rules, and then I have to put it all together. I also get very lost with implicit   differentiation. These often have fractions with different denominators and ugly numerators. I would love to have a little bit of tutoring on the weekends. I really think this will make my brain better overall if I can do more and more in my head.

My blindness occurred a few years ago so I am not up to par with braille. I have been using math player to read my equations. One of my biggest struggles is interpreting tactile graphs. Another one of my struggles is making sure I am typing my work on Microsoft word in a way that my teacher understands it. Keep putting forth the effort with calculus! I always say to give something a try and figure out whether or not it’s possible or whether or not it’s something worth trying. Keep at it! I’ll try to keep at it too!

>>> When I learned calculus I was a low vision person, not totally blind.  I did not use braille.  Now that I am totally blind I can understand the desire to work in braille, but there is a problem in that so much of calculus instruction is based on graphs, which are poorly supported in the tactile display world.  One thing you have described is a shortage of braille display space for your equations.  There are several braille displays available that will handle many lines of braille that might ease your problem.  The TI84 graphical calculator abailble from APHB might help also. Good luck.
