Using the unit circle definition has the advantage that the angle can be extended to any real argument. The sine function is 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.
Also notice that the graphs of sin, cos and tan are periodic. +

C The definition of the sine function for complex arguments z: where i 2 = −1, and sinh is hyperbolic sine.

Sine can also take a complex number as an argument. ∑ {\displaystyle a} Move the mouse around to see how different angles (in radians or degrees) affect sine, cosine and tangent.

| Cosecant gives the ratio of the length of the hypotenuse to the length of the opposite side:[1].
In mathematics, the sine is a trigonometric function of an angle. = ) It is possible to express any trigonometric function in terms of any other (up to a plus or minus sign, or using the sign function). {\displaystyle {\tfrac {\sin(\theta )}{\cos(\theta )}}} ( Notice also the symmetry of the graphs.
The CORDIC algorithm is commonly used in scientific calculators. While the early study of trigonometry can be traced to antiquity, the trigonometric functions as they are in use today were developed in the medieval period.
0 For applications involving angle sensors, the sensor typically provides angle measurements in a form directly compatible with turns or half-turns. ( is 2 sin
[9] Al-Khwārizmī (c. 780–850) produced tables of sines, cosines and tangents.

Many other trigonometric functions are also defined in math.h, such as for cosine, arc sine, and hyperbolic sine (sinh). n

This integral is an elliptic integral of the second kind. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it 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). The following table gives basic information at the boundary of the quadrants. is the derivative of

These apply for all values of

{\displaystyle \Gamma }
The accuracy advantage stems from the ability to perfectly represent key angles like full-turn, half-turn, and quarter-turn losslessly in binary floating-point or fixed-point. π = Therefore, in most branches of mathematics beyond practical geometry, angles are generally assumed to be expressed in radians.

and )
This means that they repeat themselves. π Turns also have an accuracy advantage and efficiency advantage for computing modulo to one period. ( A once common programming optimization, used especially in 3D graphics, was to pre-calculate a table of sine values, for example one value per degree.

In contrast, representing A right-angled triangle is a triangle in which one of the angles is a right-angle. Furthermore, if
For example, the C standard library defines sine functions within math.h: sin(double), sinf(float), and sinl(long double). Therefore sin(ø) = sin(360 + ø), for example. π
Description The java.lang.Math.sin (double a) the trigonometric sine of an angle. π [9] With the exception of the sine (which was adopted from Indian mathematics), the other five modern trigonometric functions were discovered by Arabic mathematicians, including the cosine, tangent, cotangent, secant and cosecant. cos

They are often shortened to sin, cos and tan.

, we have ) {\textstyle {\frac {\pi }{\sin(\pi z)}}} Using the reflection from the calculated geometric derivation of the sine is with the (4n+k)-th derivative at the point 0: This gives the following Taylor series expansion at x = 0.
Complex sine functions are also available within the cmath module, e.g. [17] The English form sine was introduced in the 1590s.
