just wondering if anyone recognizes a general formula with 2 variables for the graphs attached. The range is $x \in [0,3]$ and $H \in (0,0.5)$. You don't have to suggest an exact formula for the graph, just a general one will do. I think I can do the scaling myself.
I have attached 6 graphs below. Notice the "title" of the graph with $H$ on top and the x axis of the graph going from $[0,3]$. I am having trouble identifying even for the 1 variable graph for $H=0.001$. Any suggestion?
