Using GMSH API, build a code that:
- Discretizes the segment [0,2π] with a mesh size of your choice
- Computes, on each node of the mesh, the cosine of the 2*x-coordinate ($=\cos(2x)$)
- Plot this function using, for example, Matplotlib
This program can obviously be done without GMSH (and way faster without!). It’s just a toy program!
