Statement (i) : sin 2 θ + cos 2 θ = 1 Statement (ii) : cosec 2 θ + cot 2 θ = 1 Which of the following is valid ?

Trigonometry identity : sin 2 θ + cos 2 θ = 1 cosec 2 θ - cot 2 θ = 1 ∴ Only statement (i) is correct. Hence, Option 1 is the correct option.

Show SolutionHide Solution↓

Trigonometry identity :

sin² θ + cos² θ = 1

cosec² θ - cot² θ = 1

∴ Only statement (i) is correct.

Hence, Option 1 is the correct option.
