Notice that N(u) yields an expression in which u is the variable of integration, and also appears in the upper limit of integration. I.e. N(u) => romberg(f(u), u, -10, B(u)) You can help Maxima by distinguishing the variable of integration, e.g. N(x):=romberg(f(uu),uu,-10,B(x))$ I find that with that definition, the plot works OK.
