Maple code:sol := proc (n) options operator, arrow; dsolve([(D(g))(r) = a(r)*g(r)/r, (D(a))(r)/r = g(r)^2-1, a(1/100000) = n, g(10) = 1], numeric) end proc;plots:-display(seq({plots:-odeplot(sol(n), [r, g(r)], linestyle = n, color = ColorTools:-Color([1/n, 1/(1+n), 1/(n+4)]))}, n = 1 .. 7));plots:-display(seq({plots:-odeplot(sol(n), [r, a(r)], linestyle = n, color = ColorTools:-Color([1/n, 1/(1+n), 1/(n+4)]))}, n = 1 .. 7));

I find that DSolve does not produce an error message but instead returns unevaluated, meaning that it cannot solve the problem..

Always edit if improvable, show due diligence, give brief context, include minimal working example of code and data you are working on in formatted form. By doing all this you help us to help you and likely you will inspire great answers. The site depends on participation, as you receive give back: vote and answer questions, keep the site useful, be kind, correct mistakes and share what you have learned | |
