Convert rectangular to spherical calculator can be a helpful tool for these students.
This is wonderful because it shows you how to solve the problem, it really-really beneficial for all, try it u won't regret downloading it, the only thing I would suggest to fix is the camera sometimes it gives you other number and you have to keep doing it again and again.
Will solve complex equations, if I am struggling to understand a question I can get step by step details, i love it so much it helps alot especialy because i have something called discalculea witch is the # form on dislexia so it comes in really handy when # are turning into letters.
Works great, very efficient, wish they had it for physics though, good app. Just great. Phenomenal app. Again a very nice app, just like walking to class instead of driving doesn't help me learn where my class is better, i love this app, I finished 10 assignments in less than 10 minutes.
