Question

The trigonometric equations which hold true for any value of the angle are known as ____________ .

• A. trignometric ratios
• B. trignometric angles
• C. trignometric identities
• D. trignometric compliments

Answer 1

The correct option is C trignometric identities

The trigonometric equations which hold true for any value of the angle are known as trigonometric identities.

Ex: $si{n}^2\theta +co{s}^2\theta =1$ is a trignometric identity as it holds good for all values of $\theta$
