For $x$ real I have a real function $F(x)$ (equal to a function I know) and a differential equation $G$ with some complex functions for which $\Re(G)=0$ and the imaginary part doesn't necessarily vanish.
desolve (even with contrib_ode=True) fails to solve real(G),F(x), though it solves G,F(x) and when substituted the solution vanishes (including the imaginary part). The solution has indefinite integrals which I suppose are hopeless to solve. Using assumptions, the solution has realpart and imagpart. 1. Is there some trick/other CAS to solve only for real()? 2. Can I numerically verify that the real part of the solution equals the known F(x) (this might not hold)? Maple 13 claims to solve it with real(), but I don't get numerical support for the solution (assuming have done it correctly). Have numerical support that the differential equation holds for the known function. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
