Among the following correct statement is

Among the following correct statement is

A
${sin}^{2} θ + \cos^{2} θ = 1, \forall θ \in R$
B
${sec}^{2} θ - \tan^{2} θ = 1, (θ \neq (2 n - 1) \frac{Π}{2})$
C
${cosec}^{2} θ - \cot^{2} θ = 1, (θ \neq n Π)$
D
All the above

Solution:

Option (A): First trigonometric identity it satisfies for all values of

θ

Option (B): Second trigonometric identity it doesn’t satisfies for odd multiples of $90 °$

Option (C): ): Third trigonometric identity it doesn’t satisfies for the integral multiple of $180 °$

Option (D): So, answer is all the above
