There is not a "correct" trigonometric ratio. The one based on right angled triangles are limited to right angled triangles and so cannot be used for angles greater than pi radians (180 degrees). This is despite the fact that the sine ratio is defined for any angle, including reflex angles or angles of negative measure.
To find the sine of an angle of measure q, draw a line that makes that angle with the positive direction of the x-axis, the angle being measured in the anti-clockwise direction. If (x, y) are the coordinates of any point on that line, then
sin(q) = x/sqrt(x2 + y2)

What is the ratio to a percent 79 to 100?
79/100*100=79% 79:100 will be the correct ratio.
All rational numbers are a ratio of two integers?
All rational numbers CAN be expressed as a ratio of two integers. They may appear, before simplification, to be expressed in other forms. For example, the rational number 1 can be written as the ratio sin(45)/cos(45) even though neither numerator nor denominator is an integer.
What does SIN mean in math?
In a right triangle, the sine of an angle (abbreviated SIN) represents a ratio between the lengths of the side opposite of the angle and the hypotenuse of the triangle. For example, in a standard 3, 4, 5 right triangle, the 2 legs are length 3 and 4, while the hypotenuse (always the longest side) is 5.
Is there a platinum ratio if there is a golden ratio?
No. There is no platinum ratio.
What is the mass ratio of pennies to nickels?
The ratio is 1:2The ratio is 1:2The ratio is 1:2The ratio is 1:2
What does sin stand for on a calulator?
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
What is the correct trigonometric ratio is for tan?
For a right angle triangle the trigonometrical ration is: tangent = opposite/adjacent
What is the trigonometric function of sin?
opposite/hypotenuse
What is the sin function?
It is a trigonometric function. It is also continuous.
How do you know which trigonometric ratio to use when finding the measure of an angle?
Sin= Opposite leg/Hypotenuse Cos= Adjacent leg/ Hypotenuse Tan=Adjacent leg/ Opposite leg
What is a reciprocal trig function?
A reciprocal trigonometric function is the ratio of the reciprocal of a trigonometric function to either the sine, cosine, or tangent function. The reciprocal of the sine function is the cosecant function, the reciprocal of the cosine function is the secant function, and the reciprocal of the tangent function is the cotangent function. These functions are useful in solving trigonometric equations and graphing trigonometric functions.
The trigonometric ratio cosine is equal to?
opposite over adjacent
What is the trigonometric ratio for Cos?
the adjacent side over the hypotenuse
What the three main trigonometric ratios mean?
sin, cos and tan
What is sin A equals 7 over 25?
It is a trigonometric equation. A = sin-1(7/25) = 0.284 radians.
Which trigonometric function has a domain of all real numbers?
y = sin(x)
Inverse trigonometric value of sin inverse 4 11?
The inverse of sin inverse (4/11) is simply 4/11.
