How to increase performance of this code for plotting a contour plot?
I have an equation which I need to triple integrate over a unit cube. The equation is
pot = NIntegrate[1/Sqrt[(x - h)^2 + (y - k)^2 + (z - l)^2], {h,-1,1}, {k,-1,
1},{l,-1,1}];
As soon as I enter …

VectorPlot3D not working as expected (but other functions for same input are)
NIntegrate[rint2def[x, y, z, h], {h, -(a/2), a/2}]
Now, I plot the ContourPlot for $z=1/4$
ContourPlot[rint3[x, y, 1/4], {x, -2, 2}, {y, -2, 2},ImageSize -> 200]
Which gives the result as
Now, plotting …

VectorPlot3D not working as expected (but other functions for same input are)
The solution to the problem is as mentioned by @chris in comments of the question
Replace the VectorPlot3D[] command which is
VectorPlot3D[Grad[rint3[x, y, z], {x, y, z}],
{x, -2, 2}, {y, -2, 2}, { …

How to plot $\left|y(t)\right|'$ where $y(t)$ is the output from NDSolveValue
I have a complex valued ODE.
ysol = NDSolveValue[{y'[x] == I Sin[y[x] Cos[x y[x]]], y[0] == .5}, y, {x, 0, 30}];
Plot[Abs[ysol[x]], {x, 0, 30}, PlotRange -> All]
The function $\left|y(t)\right|$ is …
