SIN. Sin is the short version of the trigonometry SINE () function. This short version is always used in equations and expressions since it takes less space. Used in an equation it might look like. sin x = 0.22. This would be interpreted as “The sine of x is 0.22”. Most mathematicians would speak it as “sine x …
The term sinusoidal is used to describe a curve, referred to as a sine wave or a sinusoid, that exhibits smooth, periodic oscillation. It is named based on the function y=sin (x). Sinusoids occur often in math, physics, engineering, signal processing and many other areas.
Graphs of Sine, Cosine and Tangent
The Sine Function has this beautiful up-down curve which repeats every 360 degrees: Mirror Images Here is Cosine and Inverse Cosine plotted on the same graph: Cosine and Inverse Cosine They are mirror images (about the diagonal)! The same is true for Sine and Inverse Sine and for Tangent and Inverse Tangent..
Sin, also called Tsumi, is anything that makes people impure (i.e. anything that separates them from the kami).  However, Shinto does not believe this impurity is the result of human actions, but rather the result of evil spirits or other external factors.

Trigonometry – Sin, Cos, Tan, Cot. Take an x-axis and an y-axis (orthonormal) and let O be the origin. A circle centered in O and with radius = 1 is known as trigonometric circle or unit circle . If P is a point from the circle and A is the angle between PO and x axis then:
sin(3): sine function
The sin() function returns the sine of x, where x is given in radians. Return Value On success, these functions return the sine of x. If x is a NaN, a NaN is returned. If x is positive infinity or negative infinity, a domain error occurs, and a NaN is returned. Errors
Symbolic sine function
Depending on its arguments, sin returns floating-point or exact symbolic results. Compute the sine function for these numbers. Because these numbers are not symbolic objects, sin returns floating-point results. A = sin ( [-2, -pi, pi/6, 5*pi/7, 11]) A = -0.9093 -0.0000 0.5000 0.7818 -1.0000.
