There's no such value. sin^(-1) only takes arguments between -1 and 1.1. The problem statement, all variables and given/known data
How would I find the exact value of sin^-1 (-9) in degrees. I have no idea how to do this.
There must be some mistake then. I'd speak to the authorities. sin^(-1) does mean arcsin, yes?This is a question in my university webwork, so I dont know if they'd give a question that wouldn't have an answer.
