Question

sin°/1-cos°=1+cos°/sin°=cosec°+cot°​

Answer 1

Answer:

1.

sin°/1-cos° = 1+cos°/sin°

sin^2∆ = (1+ cos°) × (1- cos°)

sin^2∆ = 1^2 - cos^2

【 sin^2∆ = sin^2 ∆】

2.

1+cos°/sin° = cosec°+cot°

1+cos°/sin°= 1/sin° + cos°/sin°

【1 + cos°/sin° = cosec° + cot° 】

Hence, proved.

Hope it helps.
