Definition & Meaning of Trigonometric Identities
Trigonometric identities are mathematical equations that establish relationships between the angles and sides of triangles, particularly in the context of right triangles. These identities are essential in various fields, including engineering, physics, and computer science. The primary trigonometric identities include:
- Reciprocal identities: These relate the sine, cosine, and tangent functions to their respective reciprocals. For example, csc(θ) = 1/sin(θ).
- Pythagorean identities: These identities express the fundamental relationship between the sine and cosine functions. An example is sin²(θ) + cos²(θ) = 1.
- Co-function identities: These identities relate the trigonometric functions of complementary angles, such as sin(90° - θ) = cos(θ).
- Even-odd identities: These describe the behavior of trigonometric functions with respect to negative angles, for instance, sin(-θ) = -sin(θ).
