Trigonometric functions are mathematical functions that relate the angles of a triangle to the lengths of its sides. They are fundamental in mathematics, especially in fields like geometry, physics, engineering, and mathematics itself. The primary trigonometric functions are: 1. **Sine (sin)**: For a given angle in a right triangle, the sine is defined as the ratio of the length of the opposite side to the hypotenuse.
