Re: [Phys-L] homework



It won't do cubic roots (3x^3-x^2/2 - x - 4 = 0 ) or transcendentals ( 3x - tan(x) = 5). It only shows the graphs. One could put in symbolic constants and have them defined elsewhere. I couldn't get the program to scan a cleanly hand-written ax^2 + bx + c = 0 , but it quickly picked up 5x^2 - 3x - 2 = 0 . Apparently, it doesn't like symbols other than x. I tried to get it to scan ax^2 by itself ( hand-written, cleanly) and it failed.

There's also a free app for Android and iPhone that uses the phone camera to look at a math problem and provides a detailed solution.

How long before a TI calculator is released with a built in camera to do this?
