We evaluate some finite and infinite sums involving [Formula: see text]-trigonometric and [Formula: see text]-digamma functions. Upon letting [Formula: see text] approach [Formula: see text], one obtains corresponding sums for the classical trigonometric and the digamma functions. Our key argument is a theta product formula of Jacobi and Gosper’s [Formula: see text]-trigonometric identities.
