If anyone could help me with this, I'd very much appreciate it.
See the attached picture called "equation". That is the differential equation I'm trying to solve. The graph (for m=1) should like as it does in the other attached picture called "graph".
I tried this
m := 1;
de := diff(y(x), x, x, x)+((m+1)*(1/2))*y(x)*(diff(y(x), x, x))+m*(1-(diff(y(x), x))^2) = 0;
DEplot(de, y(x), x = 0 .. 8, [[y(0) = 0, (D(y))(0) = 0, (D(y))(infinity) = 1]], y = 0 .. 1);
But goes this error message
Error, (in DEtools/DEplot/CheckInitial) initial point in all initial conditions must be the same
I don't know how to get around this because my initial conditions are what they are, I can't change them.
Does anyone know of a way to fix this or know of a better way? The reason I need this is because I need to get the graph for m=0.77, which isn't in those photos.
Any help is appreciated.
