We present an efficient solution to the following problem, of relevance in a numerical optimization scheme: calculation of integrals of the type EQUATION for quadratic polynomials f, φ1, φ2 on a plane triangle T. The naive approach would involve consideration of the many possible shapes of T ∩ {f ≥ 0} (possibly after a convenient transformation) and parameterizing its border, in order to integrate the variables separately. Our solution involves partitioning the triangle into smaller triangles on which integration is much simpler.
