Answer:
Step-by-step explanation:
tan theta-cot theta=0
tan theta-1/tan theta=0
(tan² theta-1)/tan theta=0
On cross multiplying...
tan² theta-1 =0
tan² theta =1
sin² theta/cos²theta=1
sin² theta=cos² theta
On taking roots in both sides
sin theta=cos theta
So, sin theta+cos theta
=sin theta+sin theta
=2 sin theta of 2 cos theta
Hope it is clear...
