the question is: find the exact value of tan 285 deg + cos 75 deg + cot 60 deg(adsbygoogle = window.adsbygoogle || []).push({});

i tried converting them to radians and got

tan 5pi / 12 + cos 5 pi / 12 + cot pi / 3

by "exact value", the question means fractions, not decimals. 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. ^_^
