Why did it do that? Did I hit a hot-key and change something? My batteries are good and show four bars. I removed a battery for a few seconds, but that didn't change anything.
Please help.
TIA!

Classpad 330 and a few basic Casio's

Everyone, my wonderful ClassPad 330 is refusing to graph Y=Sin(X). I have been using variations of the trig. functions for a while. Now, when I try to graph a sine wave, it gives me a slightly positive linear line. Cosine is the same graph, etc.
Why did it do that? Did I hit a hot-key and change something? My batteries are good and show four bars. I removed a battery for a few seconds, but that didn't change anything.
Please help.

I don't know, but check the angle unit (Menu at the top left corner, then Basic format ; check that Radian is not selected instead of Degree for instance) and/or try to change the View Window (or graph sin(x), then click Zoom, Quick Trig).
