What does SIN mean?
Sin or sine is a trigonometric function that represents the ratio of the length of the opposite side of that angle to the length of the longest side or hypotenuse of a right-angle triangle. If an angle of a right angle triangle is B, then sinB is defined as opposite/hypotenuse.
The sine function is one of the six main trigonometric functions. The others are cosine, tangent, cotangent, secant and cosecant.
History
The sine function is closely related to the ‘jyā’ function of the ancient Gupta period. In the 9th century, the function is used in Islamic Mathematics to solve triangles. Later, in 1748, Euler’s formula of Leonhard Euler defined the six trigonometric functions as infinite series and presented the abbreviations sin, cos, tan, cot, sec, and cosec.

The value of the sine function is always positive in the first and second quadrants as the values from sin0° to sin180° are positive, while negative values of sine function are found in the third and fourth quadrants.
Sine graph
The graph for y = f(x) = sin(theta) is given below where for any values of x, the value of f(x) oscillates from -1 to +1.
Law of sine function
The ratios of the lengths of sides and the sine functions of the opposite angles of a triangle are always the same.
If the length of the sides of a triangle is a, b and c and the opposite angle of those sides of the triangle is A, B and C respectively. Then, the Sine law is derived as –
sinA/a = sinB/b = sinC/c
Some basic formulae of sine –
- sin2x + cos2x = 1
- sin(A+B) = sinAcosB + cosAsinB
- sinP + sinQ = 2sin((P+Q)/2)cos((P-Q)/2)
- sin2M = 2sinMcosM
Uses
The six functions including sine are applicable in electrical engineering, GPS, flight, architecture, land surveying, music, trajectories, etc.
