It is then applied to compute (i) the inner product between the basis states and (ii) an algebraic formula for the Clebsch-Gordan coefficients. These were obtained earlier by us using Gaussian integration techniques.RevTex 3.0, 30 pages, no figures; Latex error correctedHigh Energy Physics - TheoryAn Auxiliary 'Differential Measure' for $SU(3)$text
