What are Trigonometric Identities?

Trigonometric Identities are equalities that utilize trigonometry functions and hold true for all variables in the equation. There are several trigonometric identities relating to the side length and angle of a triangle.

Given a few trigonometric equations and it is needed to check which equation is an identity. Since Trigonometric Identities are equalities that utilize trigonometry functions and hold true for all variables in the equation. Therefore, the equations that are identities are,

C.)

sin²x + cos²x = 1

sin²x = 1 - cos²x

D.)

sec²x - tan²x = 1

sec²x - 1 = tan²x

tan²x = sec²x - 1

Hence, the correct options are C and D.
