And what was it you wanted to do with this cute little trigonometric function? Exactly what part of "Write clearly! We are not mind readers, so be sure to ask a question that we can understand" is it that you don't comprehend? This is the text that is in the field where you wrote your function, so there is no excuse whatsoever for not reading it. This is Algebra.com. It is NOT and never will be the Psychic Hot Line.
