I am trying to graph a very simple wave (2 sin x) but for some reason, no matter what 'x' I use, it says either 'syntax error' or 'maths error'
Help please

I just tried it. It worked for me. All I did was press the number 2, then sin, then x (the blue button, next to log, top left).
Try "initialising all" or just the main memory and setup data if you have data/addins.

Make sure your calc is in Radian or Degree mode ;)
