Substituting the boundaries directly accelerates the process since we do not have to substitute back to the original variables: Z b a g(u(x))u′(x) dx= Z u(b) u(a) g(u) du. Proof. This identity follows from the fact that the right hand side is G(u(b)) − G(u(a)) by the fundamental theorem of calculus. 웹Back substitution to obtain δ x G, δ x τ and δ x Q → i.
