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.
