Question

Prove that sin theta / 1 -cos theta =cosec theta +cos thetha

Answer 1

Answer:

Step-by-step explanation:

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.
