so i've been working on some extra credit that's not due til the end of the week. My teacher said we could work with others so this isn't cheating. Right? Anyway, I cant find the derivative of y = 1.8sin^3((pi/12)x - (pi/2)) + 98.6

Sorry about the text, I cant find out how to get the pi symbol. I've tried this multiple times and can't come out to the right answer(Checked on Wolframalpha). If someone could please help I would much appreciate it.
