The conical product rules for integration over a triangle ABC are well known. In this note, we discuss conical product rules with weight function w(x)r/sup ..beta../ where r is the distance of (x,y) from C and x is the distance of (x,y) from AB. In particular we show how to construct rules which are exact for integrand functions p/sub lambda/(x,y)h/sub ..mu../(r) where p/sub lambda/ and h/sub ..mu../ are polynomials of degree lambda and ..mu.., respectively.
