👉 Trigonometry is a branch of mathematics that studies triangles and their relationships to the sides, angles, and other characteristics of these figures. It includes topics such as trigonometric functions (such as sine, cosine, tangent, secant, cosecant, cotangent), right triangle trigonometry, hyperbolic trigonometry, and polar coordinates.
In trigonometry, angles are defined in terms of radians, which is a mathematical unit used to measure the size of angles. Angles
