Full Version: HP 50g graphing ABS(X)

I have a weird problem on the 50g. Trying to graph 'ABS(X)', the graph plots a straight line through the origin. Any idea what could be wrong?

EDIT: I've solved it. It turned out that I had 'Rigorous' unchecked in the CAS menu, so |X| was being simplified to X.
