Answer:
1-tan theta = sec theta
sec theta = 1 / cos theta
sin theta = 1- cos² theta
= (1+cos theta)( 1-cos theta)
cos theta / 1- tan theta + sin theta / 1- cos theta
= (cos theta × 1/ cos theta) + (1+cos theta)( 1-cos theta) / 1-coa theta
(cancellation of similar terms)
= 1+1+cos theta = 2+ cos theta
answer :
= 2+ cos theta
