👉 In mathematics, trigonometry is a branch of geometry that studies triangles and their relationships with circles. It involves the study of angles, lengths, and distances between points in space. Trigonometric functions are ratios of two sides of a right triangle, often used to find the properties of these figures such as area and perimeter. The most well-known trigonometric function is sine, which relates an angle and its ratio to the length of a side of a triangle. Other important trigonometric functions
