RE: Plot more than two functions
With the HP Prime in CAS Mode I am trying to plot on one screen the Function, the First Derivative and the Second Derivative to interpret Concavity and Points of Inflection of the function.
For example: √ F1(X): 2*(X²9)/(X²4) √ F2(X): ∂F1(X)/∂X=X √ F3(X): ∂F2(X)/∂X=X Upon pressing the Plot key my plot shows F1(X), F2(X) and F3(X) simultaneously on the Plot screen correctly. However, upon pressing the Num key the X, F1, F2, F3 cells are blank. E.g. ___________________  X  F1  F2  F3         Please tell me what I am doing incorrectly so that I may see all three functions numerically. Also, should I install the November Beta Release? If so where do I find the procedure for stepbystep instructions? Thanks Thomas – Cheers!
