Let f be a function analytic in a multiply connected region, D, containing the simple closed contour C. Approximations to the contour integral of f around C by weighted sums of function values are ...

Covers asymptotic evaluation of integrals (stationary phase and steepest descent), perturbation methods (regular and singular methods, and inner and outer expansions), multiple scale methods, and ...
