I'm lost on the following usage of the Mesh and MeshFunctions options to Plot, using them to show the intersection of two functions, f and g:
Mesh->{{0}}
MeshFunctions -> {(f - g) /. x -> # &},...
The whole thing looks like this:
1. Define two functions:
{f, g} = {Sin[2 x], 1/2 Cos[5 x]};
2. Plot them showing intersection with large points:
Plot[{f, g}, {x, 0, 2 \[Pi]}, Mesh -> {{0}},
MeshFunctions -> {(f - g) /. x -> # &},
MeshStyle -> PointSize[Large]]
I have a basic understand of pure functions but the usage here baffles me.
Thanks for any help.
