Extremums on Prime Message #1 Posted by Richard Berler on 12 Oct 2013, 6:58 p.m.
I just discovered how to quickly find extremums of a function...I enter function in functions app (make sure you check mark it, and de check other functions) copy the function, go back to home and get zeros from cat, call up d?/dx from entry template key, paste in the function that I just copied, and hit enter. This gives me potential extremums. Then, go to setup plot, and put in an x range that is fairly tightly centered on a zero, hit view, hit auto scale, and the graph comes up, touch screen near extremum, go to menu, function, extremum! Quick and easy!
This shows how outstanding the graphing capability on this unit is...nice!
