If n is an integer, n * 180 degrees represents an integer multiple of 180 degrees, (2n + 1) * 90 degrees represents an odd integer multiple of 90 degrees, and so on. Decide whether each expression is equal to 0, 1, -1, or is undefined ?

csc[(4n+1) * 90degrees]

Any help provided on this would be very appreciated!
