1. The problem statement, all variables and given/known data I need to find the inverse of the following matrix: [(cos*sin) (-cos) (sin2)] [(cos2) (sin) (-cos*sin)] [(sin) 0 (cos)] 2. Relevant equations gauss-jordan elimination 3. The attempt at a solution I know that in general, gauss-jordan elimination can be used to solve the inverse of a 3x3, but given this matrix, I don't see how that method could be particularly useful or efficient. I tried to get started using gauss-jordan but expressions quickly became to large to deal with. Are there any slightly less involved ways to find the inverse here?
