Question

The value of 9 cot²θ -9 cosec²θ is 9.​

Answer 1

Yes. the value of 9 cot² θ - 9 cosec² θ = 9

➡ 9 cot² θ - 9 cosec² θ

➡ 9(cot² θ - cosec² θ)

• cot² θ - cosec² θ = 1

➡ 9(1)

➡ 9

# Hence,it is proved.

Information :-

◼ sin² θ + cos² θ = 1

◼ cot² θ - cosec² θ = 1

◼ sec² θ - tan² θ = 1
