How to mark a specific line in ContourPlot
I have the next differential equation
sol = ParametricNDSolve[{y'[t] == a y[t], y[0] == 1}, y, {t, 0, 10}, {a}]
And a Contour Plot of this equation
ContourPlot[y[a][x] /. sol, {x, 0, 0.1}, {a, 0 …

Implementation of filling (Colour) [closed]
I have a question. When I use "Filling"
Plot[Evaluate[{x^2, x}], {x, 1, 2}, PlotRange -> All, Filling -> {1 -> {2}}]
One of the functions appears in orange and the other one in blue, there is some w …

Combining "Do" and NDSolve
I have following code:
Two differential equations,each one of them with varying initial conditions
Clear["Global`*"]
sol1[l0_] := NDSolve[{D[r[x]/(1 + x)^4, x] == 0, r[l0] == 2}, r, {x, 0,1000}, Ac …

Combining "Do" and NDSolve
The suggestion of @MarcoB was really helpful.
This is my propose of solution:
Clear["Global`*"]
sol1[l0_] := NDSolve[{D[r[x]/(1 + x)^4, x] == 0, r[l0] == 2}, r, {x, 0,1000}, AccuracyGoal -> 15];

Extracting a function from a Contour Plot
Context to understand the question
Suppose that I have the next equation
sol = ParametricNDSolve[{y'[t] == a y[t], y[0] == 1}, y, {t, 0, 10}, {a}]
And I make a Contour Plot of this equation
Cont …

Two different solutions for the same ContourPlot while using AccuracyGoal and WorkingPrecission
I was making a contour plot, of some differential equation however I get two different solutions If I use "AccuracyGoal" and "Working Precision". The question will appear long but most of the post is …

Peculiar behaviour in the implementation of “Filling”
I was working with mathematica and I need to use "Filling", however I notice that it doesn't work when you have "small" numbers, for example if I make the following:
Plot[Evaluate[{x + 1, x + 2}], {x, …
