Graph App

[lrdheat]

Would it be possible to add the capability of saving multiple POI's on the soft menu on the graphing app? It would be quite handy when finding signed area under a curve from , say, first root to next root, or area between curves from first intersection to second intersection. If I understand the graphing app properly, I have to from the app to home to save a root, for example, into a variable, and then return to the app and find the next root (the new root replaces the old root in the root result variable). I can then use my saved variable from home as the lower x value, and the result root variable for my upper x value over which to find the signed area. For POI's that were intersection of 2 functions, I would want the ability to use the x value from (x,y) that describes the POI (in this case, intersection of two functions).
