🔑 Key Concepts & Definitions

Sine (sin): A ratio of the lengths of sides in a right triangle, specifically the length of the side opposite the angle divided by the length of the hypotenuse. It provides a fundamental relationship between an angle and the side lengths in right-angled triangles.

Cosine (cos): A ratio of the lengths of sides in a right triangle, specifically the length of the side adjacent to the angle divided by the hypotenuse. It establishes a key connection between an angle and the side lengths in right triangles.

Tangent (tan): A ratio of the lengths of sides in a right triangle, specifically the length of the side opposite the angle divided by the length of the side adjacent to the angle. It relates an angle to the ratio of two sides in right triangles.

Reciprocal functions: These are functions derived from the basic trig functions by taking their reciprocals. Cosecant (csc) is the reciprocal of sine, secant (sec) is the reciprocal of cosine, and cotangent (cot) is the reciprocal of tangent. They extend the basic relationships and are useful in various identities.
