I'm trying to illustrate the solutions numerically and graphically for an equation such as
Tan[x] == x. I think I did everything ok except I wanted to mark each intersection between
Does anyone know how such a thing can be done?
Edited to make it a function.
For the strange
You can also use

Update 2: Using just
See also the solution using RootsInRange. This solution is more general as it will work when either the exact intersections are not known, or NSolve fails.
