How to find the CSC 120 AND COT (-120)?

what does cst and cot stand for? anyway, im sure u had some sort of work to get ur answers. if not, then try to do the inverse operations of whatever should be done, therefore getting the beginning in the end. for 1, m guess is u came to 2/x=radical 3. for 2 u probably got 1/x=radical 3?
