1. cosine

   In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse. For an angle θ {\displaystyle \theta } , the sine and cosine functions are denoted simply as sin ⁡ θ {\displaystyle \sin \theta } and cos ⁡ θ {\displaystyle \cos \theta } .More generally, the definitions of sine and cosine can be extended to any real value in terms of the lengths of certain line segments in a unit circle. More modern definitions express the sine and cosine as infinite series, or as the solutions of certain differential equations, allowing their extension to arbitrary positive and negative values and even to complex numbers. The sine and cosine functions are commonly used to model periodic phenomena such as sound and light waves, the position and velocity of harmonic oscillators, sunlight intensity and day length, and average temperature variations throughout the year. They can be traced to the jyā and koṭi-jyā functions used in Indian astronomy during the Gupta period.

1. cosine

   Cosine is a mathematical function that describes a specific relationship between the angles and sides of a right triangle. It is defined as the ratio of the adjacent side to the hypotenuse in a right-angled triangle. Cosine is also commonly used in trigonometry and complex numbers and its value ranges from -1 to 1. The cosine of an angle is found by plotting the angle in a unit circle and measuring the horizontal distance from the origin to the point on the circle.
