This will typically be called directly from antiD()
when an
integral can't be handled symbolically.
create_num_antiD(tilde, ..., lower = NULL, .tol = 1e-04)
a function with the w.r.t. variable as the first argument. The function is a wrapper around numerical integration routines.
Tilde expression for the function to be anti-differentiated. Right-hand side will be the w.r.t. variable
arguments and parameters to the function described by tilde
Optional lower bound of integration. Useful to avoid domain problems with the function being integrated, but not generally needed.
Numerical tolerance for the integration
