Abstract
There is a beautiful cubic analogue of Jacobi's fundamental theta func tion identity: theta3(4) = theta4(4) + theta2(4) It is [GRAPHICS] Here omega = exp(2pii/3). In this note we provide an elementary proof of t his identity and of a related identity due to Ramanujan. We also indic ate how to discover and prove such identities symbolically.
