to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A

### How do you use sine in math?

The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle… Read More

### State the Sine Law in words?

The formula is a/sinA=b/sinB=c/sinC. The idea behind the equation is that the larger an angle is the larger the side across from it will be and the smaller the angle the smaller the side across from it will be.

### Is sine of an angle directly proportional to an angle?

No. The sine of an angle is not directly proportional to the angle. It is a function of the angle, but it is periodic, repeating every 360 degrees of the angle.

### What is the the correct trigonometric ratio of sin?

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… Read More

### How do you figure out the sine of a triangle?

An angle can have a sine ratio, not a triangle.

### What is the value of the sin?

If you mean the sine function, it is dependent on an angle. For example, the sine of an angle of zero degrees is zero; the sine of an angle of 90 degrees is one; for an angle of 180 degrees, the sine is again 0; if you make a graph, you get a curve that looks like a wave. In general, the values the sine function can take are between 1 and -1, inclusive.

### What does sine theta mean?

Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.

To find which angle has a sine of 0.13, you calculate arcsin or sin^-1(0.13) =7.47 degrees 7.47 degrees has a sine of 0.13. There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180. 180-7.47 = 172.53 degrees also has a sine of 0.13.

### Does the sine of an angle decreases as the angle increases from 0 degrees to 90 degrees?

No. As the angle increases from zero to 90 degrees, its sine increases from zero to '1'.

### What is the value of sine theta when theta is equal to 0.4384?

We'll answer your question as asked. What was asked was, "What is the sine of the angle (the angle theta) if the angle measures 0.4384?" That's the way the question reads. That's a pretty small angle. Less than one degree. That angle has about 0.00765 as the sine. Perhaps the question was "What is the angle of theta if its sine is 0.4384?" In the event that this was really your question, if sine theta… Read More

### What is angle a when given sin a 312?

The absolute value of the sine function cannot exceed 1 and so sin(a) = 312 is not possible.

### Relationship between angle of refraction and refractive index?

The relation between the angle of refraction and refactive index is: Sine i/Sine r=Refractive index where,i=angle of icidence r=angle of reflection

### A is an angle whose sin is 37 and whose secant is negative Its vertex is the origin and one side is the positive x axis. What quadrant does the terminal side of the angle reach?

There is no such angle, since the sine of an angle cannot be greater than 1.

### What ratio correctly describes the sine function?

In a right triangle, the sine of an (non right angle) angle would the ratio of the opposite side (opposite to the angle selected) and the hypotenuse

### How do you find an angle measurement of a triangle?

The answer depends on what information you have, If you know only the lengths of the sides, you use the cosine rule to find the measure of one angle and then the sine rule to find the other angles.

### How do you determine sine in a right triangle?

The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.

### Which ratio is used in finding the sine of an angle in a right triangle?

It is: sine = opposite/hypotenuse

### How do you calculate the angle if you know Sin of the angle?

type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine

### Is the sine of an acute angle is greater that 1?

No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.

### In a right triangle the sine of any angle is?

The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.

### A ski slope is 250 yards long with a vertical drop of 100 yardsfind the angle of depression of the slope?

The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees

### Why is the sine of 90 degrees equal to 1?

Sine = Opposite divided by Hypotenuse Opposite is the side of the triangle opposite the angle (in this case the 90o angle). Hypotenuse is the side opposite the right angle in a right angle triangle. Therefore, Sine 90 = 1 because the opposite side and the hypotenuse are the same side, they are both opposite the right angle.

### Does the index of refraction equal the angle of refraction?

Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index

### How to calculate the sides of a triangle given the degree of an angle and one side?

The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.

### A sentence using the word sine die?

First of all, a sine is the trigonometric function that is equal to the ratio of the opposite a given angle to the hypotenuse. The teacher told us to use the word sine in a sentence. He told us what a sine is and how you use it. A sine is the trigonometric function that is equal to the ratio of the opposite a given angle to the hypotenuse.
