ON SOME SUM–TO–PRODUCT IDENTITIES SHAUN COOPER AND MICHAEL HIRSCHHORN We give new proofs of some sum–to–product identities due to Blecksmith, Brillhart and Gerst, as well as some other such identities found recently by us. 1. INTRODUCTION AND STATEMENT OF RESULTS In the first two ...
They include the fundamental identities for theta functions such as Jacobi's triple product identity, the quintuple product identity, Ramanujan's summation formula, and the q -binomial theorem. We also encounter generalizations of the sine and cosine functions. A study of the coefficients in their ...

products or products into sums can make a difference between an easy solution to a problem and no solution at all. Two sets of identities can be derived from the sum and difference identities that help in this conversion. The following set of identities is known as theproduct‐sum identities...
individual ratios. These identities are derived by adding or subtracting the sum and difference formulas for sine and cosine. It is a good idea to memorise these identities if we can since they will help us reduce more complicated trigonometric problems and help us prove other trigonometric ...

While solving trigonometric problems, one needs significant trigonometric identities and formulae such as half-angle formulae, sum/difference identities, Pythagorean identities, etc. A few sum/difference identities are listed below: sin(A+B)=sinAcosB+cosAsin...
N-graphs, modular Sidon and sum-free sets, and partition identities We extend the concepts of sum-free sets and Sidon-sets of combinatorial number theory with the aim to provide explicit constructions for spherical designs. We call a subset S S S of the (additive) abelian group G G G {...
