This is not a homework help problem but I believe this question belongs here more so than in the other forums.
I would like to (for personal benefit) duplicate / generate the plots in Figure 2.6 of Griffiths Quantum Mechanics book - page 55, 2nd edition.
The Attempt at a Solution
I apologize - I have no attempted solution (yet).
I do not want to buy any s/w if that is required.
I believe the big picture for the plots is to show solutions that "blow-up" for certain energy levels and not for the reader to generate the plots.
I see the x-axis is the dependent variable (not sure which symbol), is the y-axis psi? - plotting equation [2.72]?
What do I need to generate this plot on my own? Can it be done in Excel?
