Trigonometry identities are mathematical expressions that relate the trigonometric functions of an angle or a ratio of sides in a right triangle. They are useful for simplifying and solving equations involving trigonometric functions. Some of the most common trigonometry identities are:

- Pythagorean identity: sin^2(x) + cos^2(x) = 1
- Reciprocal identity: sin(x) = 1/csc(x), cos(x) = 1/sec(x), tan(x) = 1/cot(x)
- Quotient identity: tan(x) = sin(x)/cos(x), cot(x) = cos(x)/sin(x)
- Cofunction identity: sin(90° - x) = cos(x), cos(90° - x) = sin(x), tan(90° - x) = cot(x), cot(90° - x) = tan(x)
- Sum and difference identity: sin(x + y) = sin(x)cos(y) + cos(x)sin(y), cos(x + y) = cos(x)cos(y) - sin(x)sin(y), tan(x + y) = (tan(x) + tan(y))/(1 - tan(x)tan(y))
