Question

Cos∅ cot∅/1+sin∅ = cosec ∅- 1

Answer 1

Answer:

hence proved

Step-by-step explanation:

let theta be "O"

=cos^2 O/ sinO (1+sinO)

= 1-sin^2 O/ sinO (1+sinO)

=(1+sinO)(1-sinO) / sinO (1+sinO)

=(1-sinO)/ sinO

=1/sinO - sinO/sinO

= cosecO - 1

Answer 2

Step-by-step explanation:

kindly refer to attachment

some hints

• cotθ = cosθ / sinθ
• (a + b) (a - b) = a² - b²
• cosecθ = 1 / sinθ
