Question

if cosec theta + cot theta = m, Cosec theta- cot theta =n.
find mn
Pls give the answer step by step and with all briefing ....​

Answer 1

Answer:

Explanation:

We have,

cosecθ + cosθ = m

cosec θ - cos θ = n

Now,

mn

= (cosec θ + cos θ)(cosec θ - cos θ)

= cosec² θ - cos² θ

= 1/sin²θ - 1/cos²θ

= (cos² θ - sin² θ)/cos²θsin²θ
