Step-by-step explanation:
it will help you dear friend
taking L.H.S
(cosec theta -cot theta)^2
cosec^2 theta+cot^2-2cosec theta*cot theta
1/sin^2 theta+co^2/sin^2-2os theta/sin theta*sin theta
1/sin theta+cos^2/sin^2 theta-2cos theta/sin^2 theta
1+cos^2-2cos theta/sin^2 theta [(a-b)^2=a^2+b^2-2ab]
(1-cos theta)^2/(1-cos^2 theta) [ sin^2 theta+cos^2 theta=1]
(1-cos theta)(1-cos theta)/(1-cos theta)(1+cos theta)
(1-cos theta/1+cos theta
