tan theta + cot theta = -2
tan theta + 1/tan theta= -2
tan sq theta + 2 tan theta + 1= 0
(tan theta + 1)sq = 0
ie tan theta +1=0
tan theta=-1
tan theta= tan 135
theta= 135 ans
tan theta + 1/tan theta= -2
tan sq theta + 2 tan theta + 1= 0
(tan theta + 1)sq = 0
ie tan theta +1=0
tan theta=-1
tan theta= tan 135
