Hello colleagues,
Would anybody know good references on numerical integration of non-polynomial functions? It would be enough for me to obtain one-dimensional rules. Of course, it could have impact for XFEM applications, but for another, improved XFEM method that we are developing.
Note that I am not talking about integrating singularities, but non-polynomial functions. Examples:
sqrt(x)
cos(x)
sin(x)
product of these.
Thanks for any help,
Stephane
