Let A be a square matrix of order n. If there exists a matrix B of order n such that AB = BA = I, where I is the identity matrix of order n, then the matrix A is said to be invertible and B is called the inverse (or reciprocal) of ..

Question : If csc( ) = -8/5, find sin( ).
I'm not sure i'm doing these right. Everytime i try, it tells me the answer is wrong. This assignment is due tomorrow so if anyone could PLEASE help me out i would greatly appreciate it!
THANKS!!! (:
Answer : csc( ) = 1/sin( ) 1/sin( ) = -8/5 so take the reciprocal of both sides sin( ) = -5/8.. More from Yahoo Answers

Answer : You don't. The inverse sin, cos, etc is not the same as reciprocal. You have to calculate the reciprocal. Sorry. QED.. More from Yahoo Answers
