 48m awarded evaluation 7h revised Why is this 2D plot so slow? explain Evaluate 15h awarded Nice Answer 19h revised ParametricPlot3D for only part of a sphere Original inequality added 19h comment ParametricPlot3D for only part of a sphere @thedude Indeed, I think you're right. I'll change it. 20h answered ParametricPlot3D for only part of a sphere 21h answered Why is this 2D plot so slow? 1d revised Partial differential equation with infinity limit Corrected omitted substitution of time 1d answered Partial differential equation with infinity limit 2d comment How to make a flowchart? I know you've already thought about this before - see Controlling TreePlot (and GraphPlot) layout issue; but in all its generality this question seems a bit too much work to fit into a single answer... Just another idea without graphs: perhaps one could adapt Circuit drawing in Mathematica to your purposes. Someone has to put in the effort, though... 2d comment Schrödinger equation for Hydrogen atom Your solution approach seems overly complicated because it still requires matching the derivatives at $RM$ after already having introduced the (not strictly valid) condition of vanishing amplitude at $10RM$. You may as well do just a single ParametricNDSolveValue up to $10RM$ and solve for the Ei that makes the amplitude vanish at the end point. Then the continuity of the function and its derivative is automatically insured. Also, SCHR2 didn't solve anything when I tried it. 2d reviewed Leave Open Changing a piecewise function into a periodic function 2d reviewed Close Easy way to create an histogram with given heights? 2d reviewed Leave Open Fitting bivariate data using FindFit Feb 9 answered sum involving binomial coefficient Feb 8 comment Suddenly all outputs begins with a newline… What to do? It could also have to do with the style sheet. Impossible to tell without additional info. Maybe send the whole notebook to Wolfram support. Feb 8 comment Double arguments and place of the underscore Don't use C - it's a reserved symbol. Feb 8 comment How to numerically solve a 1-d time-independent Schrodinger equation? @Peltio I know, it's really funny... who said that reading scientific articles can't be amusing? And it shows why sites like this are needed. Feb 8 comment Restrict Locator to a certain graphic inside Manipulate @shrx The locator is restricted to the right plot region. I just tried it. It does move to the edge of the region if you click as you describe, but it never leaves that region. Feb 8 revised How to numerically solve a 1-d time-independent Schrodinger equation? Answering another part of the question.
