Locking Calculated points on a graph

[G. Cook]

On Prime G2,when finding "Signed Area" on a graph, how do you lock (or save) x coordinates of graph roots (or intersections) for use in Signed Area process?

If you're at a point of interest in a Function Plot view, pressing the Copy key (shift-View) will bring up a choice of things to copy: select the "X" choice to copy the current X value. This can be done right after jumping to a root via Fcn / Root (while the "+" / "Root: ..." / "OK" menu is still up).

If you've one (or several) X coordinates of interest copied, you can then jump to one of them while in Signed Area mode if you press the "Go To" menu key and then press the Paste key (shift-Menu) while the "Go To" dialog is open (just select the copied X coordinate of interest from the Paste choices).
