Find the EXACT trig values For undefined answers input undef

Find the EXACT trig values. For undefined answers, input \"undefined\" (without the quotes, of course). tan(120 degree) = cot(120 degree) = tan(210 degree) = cot(210 degree) = tan(150 degree) = cot(150 degree) = tan(60 degree) = cot(60 degree) = tan(240 degree) = cot(240 degree) = tan(30 degree) = cot(30 degree) = tan(135 degree) = cot(135 degree) = tan(315 degree) = cot(315 degree) = tan(0 degree) = cot(0 degree) = tan(90 degree) = cot(90 degree) =

Solution
