Question

how to solve this sin theta /1-cos theta =cosec theta +cot theta

Answer 1

here is ur answer

LHS= sin$/1-cos$
= sin$(1+cos$)/(1-cos$)(1+cos$). multiplying both with 1+cos$.
= sin$(1+cos$)/(1-cos2$)
=sin$(1+cos$)/sin2$
=1+cos$/sin$
=1/sin$+cos$/sin$
=cosec$+cot$
=RHS hence proved.
hope this may help.
