Abstract
The operator trigonometry of symmetric positive definite (SPD) matrices is extended to arbitrary invertible matrices A and to arbitrary invertible bou nded operators A on a Hilbert space. Some background and motivation for the se results is provided. (C) 2000 Elsevier Science Inc. All rights reserved.
