Plotting absolute value functions on the 50G
Is there a way to correctly plot an absolute value function (y(x) = abs(x) for example)
on the 50G? It appears that when calculating the plot points, the absolute value
is ignored and negative values are plotted as negative values.

Works fine on mine, I get the expected V shape?

+1

I ploted abs (cos (x)) and abs (inv cos (x)) togheter

Worked fine in 50g and 48's.

Flag 119 ?

I never quite understood why we wouldn't want to be rigorous?

Thanks for the help. Yes, I had the rigorous flag unchecked in CAS settings.
