I have the casio FX-83ES (the one most people have) and I can't change the setting back to normal from radians?!! Somebody help, I have a mechanics paper to do!! Pressed shift and mode/setup but then it says Normal 1-2?
You know you can do the conversion on your calculator? In other news, there's usually a button with a degree and a radian symbol on it, try that, you might be suprised
