Title: drawing absolute functions on cas
Post by: Nomvalt on April 05, 2010, 02:51:07 am

hi there, how do you draw an absolute value function on a cas calculator? I've tried following the instructions to my textbook (math quest, p.95) but in the graphs and geometry page it keeps displaying an error message saying syntax everytime I do so. Anyone out there able to help?

The command to enter an absolute function is abs(equation goes here). Alternatively, you can press ctrl and the multiplication button to get a menu, and choose the standard |equation| format.
