There are a number of different ways, depending on (a) the circumstances and (b) your mathematical sophistication.
The answer for a school student is likely to be based on a right angled triangle. At that level of knowledge, the sine of one of the acute angles is defined as the ratio of the opposite side to the hypotenuse.
On the other hand, the answer from a pure mathematician may well be
sin(x) = x - x3/3! + x5/5! - x7/7! + ... where x is the angle measured in radians.
sine and cosine
Divide -900 by 360, and the remainder will be the angle you need to find the sine of: -900 / 360 = -2.5 --> -900 = 360*(-2 - 0.5), so sine(-180°) = sine(-900°). sine(-180°) = 0
Sine ratio = opposite/hypotenuse
The maximum of the sine and cosine functions is +1, and the minimum is -1.
sine[theta]=opposite/hypotenuse=square root of (1-[cos[theta]]^2)
Sine is a law in math that helps you find the length or angles in a triangle.Sin Equals:1/YLaw of Sines:Sin A/a = SinB/b = SinC/cCosine, tangent, cotangent, secant and cosecant are also used to find sides and angles of a triangle.

Sine and cosine
In a right angle triangle divide the opposite by the hypotenuse to find the sine ratio.
Divide -900 by 360, and the remainder will be the angle you need to find the sine of: -900 / 360 = -2.5 --> -900 = 360*(-2 - 0.5), so sine(-180°) = sine(-900°). sine(-180°) = 0
In Irish 'sine' translates as 'nipple, teat'; it also means 'link' as in 'sine de shlabhra', link of chain.With a long mark over the 'i', Sìne is the Scots Gaelic version of "Jean, Jane, Sheena'.
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
Using its Taylor-series.
To find the sine ratio of a right-angled triangle divide the opposite by the hypotenuse. For example: 4/5 = 0.8 units and sine-1(0.8) = 53.13010235 degrees.
Sine ratio = opposite/hypotenuse
sin is everywhere. The Bible will teach you what it is, and you will see it all over the place. Now if you are looking for mathematical instructions for a trigonometry class about finding a sine, cosine, and tangent... I can't help you. Find a math tutor.
