The Ratios is
Sin(angle) = opposite/ hypotenuse.
It is the sine ratio.
The ratio between the opposite side and the hypotenuse in a right triangle is known as the sine of the angle opposite the opposite side. Mathematically, this can be expressed as ( \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} ). Therefore, for a given angle ( \theta ), this ratio is equal to the sine of that angle.
Sine ratio = opposite/hypotenuse
It's Sine!
This ratio is called the sine ratio for a right triangle. A simple way to remember this is by using the mnemonic 'SOHCAHTOA', where SOH stands for sine equals the ratio opposite side/ hypotenuse, COH is cosine equals adjacent side/hypotenuse, and TOA is tangent equals opposite side/adjacent side.

Opposite over hypotenuse. Sin=opposite/hypotenuse cos=adjacent/hypotenuse tan=opposite/adjacent
Sin(Sine) is a cyclic curve. This cyclic curve(wave) that repeats every 360 degrees ( or 2pi radian). Its Amplitude ranges from (+)1 to (-)1 When learning about trigonometry(Trig.) you only learn the bit between 0 degrees and 90 degrees. On extending this learning you will find it to be a cyclic curve. The word 'Sine'(Sin) is from Latin and means 'curve'. The word 'Cosine(Cos) means 'complimentary sine' . It is the same curve as Sine but shifted along the x-axis by 90 degrees.
its the cosine.. thanks to the dude up there i got it wrong and that was my answer for 4.1.3.
Sine = opposite / hypotenuse
Sine
sine
in a right trianlge the tangent is the ratio of Opposite/Adjacentcosine is Adjacent/Hypotenusesine is Opposite/Hypotenuse
The side opposite the 30° angle is 1/2 the hypotenuse or 0.5 hThe side opposite the 60° angle is (sin60°) times the hypotenuse or about 0.866 h
Sine ratio = opposite/hypotenuse
It's Sine!
