Question

my question is that- root sec theta-1/ sec theta+1 + root sec theta+1/ sec theta-1= 2 cosec theta

Answer 1

change to cos theta form

then rationalize 1+ cos theta and 1- cos theta respectively from both terms then we get 1- cos theta÷ sin theta + 1+ cos theta ÷sin theta. take sin theta LCM THEN we got the answer 2 cosec theta
