Question

sin theta /1-cos theta = cosec theta+ cot theta​

Answer 1

Answer:

Here

Step-by-step explanation:

let theta be x otherwise this will be too long

sinx/1-cosx=cosecx+cotx

Multiplying by 1+cosx on the lhs

sinx(1+cosx)/1-cos^2x

(sinx+sinxcosx)/1-cos^2x

sin(1+cosx)/sin^2x

(1+cosx)/sinx

1/sinx+cox/sinx

cosecx+cotc=R.H.S
