Answer:
Hope it's helpful!! here is answer.
Step-by-step explanation:
I will consider theta as A.
LHS= sinA
1-cosA
Multiplying numerator&denominator by 1+cosA
= sinA(1+cosA).
(1-cosA)(1+cosA)
= sinA(1+cosA)
1²-cos²A
=sinA(1+cosA)
sin²A
=1+cosA
sinA
= 1. + cosA
sinA. sinA
=cosecA+cotA
=RHS
Hence proved.
