FAQ

Q: What is a trigonometric identity?
A: A trigonometric identity is an equation that relates the values of basic trigonometric functions.

Q: What are some common trigonometric identities?
A: Some common trigonometric identities include the Pythagorean identities, reciprocal identities, quotient identities, and co-function identities.

Q: What is the Pythagorean identity?
A: The Pythagorean identity is sin^2(x) + cos^2(x) = 1, which relates the values of sine and cosine.

Q: What are reciprocal identities?
A: Reciprocal identities are equations that relate a trigonometric function to its reciprocal. Examples include sin(x) = 1/csc(x) and cos(x) = 1/sec(x).

Q: What are quotient identities?
A: Quotient identities are equations that relate a trigonometric function to the quotient of two other trigonometric functions. Examples include tan(x) = sin(x)/cos(x) and cot(x) = 1/tan(x).

Q: What are co-function identities?
A: Co-function identities are equations that relate a trigonometric function to its complement or supplement. Examples include sin(x) = cos(90° - x) and tan(x) = cot(90° - x).
