We can use the product-to-sum formulas to rewrite products of sines, products of cosines, and products of sine and cosine as sums or differences of sines and cosines. See (Figure), (Figure), and (Figure). We can also derive the sum-to-product identities from the product-to-sum ide...

From the factor graph model we can easily derive recursive formulas for symmetric loss networks. Most importantly, for any loss network we can apply efficient message passing algorithms like the sum-product algorithm to compute the marginal distributions and the blocking probabilities of all call ...
