the question is: find the exact value of tan 285 deg + cos 75 deg + cot 60 deg
i tried converting them to radians and got
tan 5pi / 12 + cos 5 pi / 12 + cot pi / 3
as far as i know, only the cot part has some special identity. am i missing something important? we have a long test tomorrow..
thanks in advance for any help. ^_^
