On a right-angled triangle, let one of the angles that is not the right angle be x. 'Sine x' is the length of the side opposite (not touching) x divided by the hypotenuse (longest side or the side that is opposite/not touching the right angle). This gives you the ratio or relationship between these two sides.
Sine-1 is the opposite; if you know the two sides (hypotenuse and opposite side) related to x, sine-1 of the opposite side divided by the hypotenuse will give you the size of angle x.
If this confuses you, sorry but it would have been much easier with a diagram. Wait until you learn trigonometry. There's only so much I can do using text.

How do you use a calculator for the law of sines say you have SinB.96 how to you get B?
well in order to get sine b you will have to got to your calculator and reverse the equation ... in other words on the calculator you will see sin-1 you will hit that and in the parenthesis you put .96 .so it should look like this sin-1(.96) and you qet your answer .!
When do you use law of sine?
There are several cases when you would want to use the law of sines. When you have angle angle side, angle side angle, or angle side side you would use the law of sines.
Does acoustics use trigonometry?
Yes, because all sound waves can be modelled as sine (or cosine) waves, or combinations of sine waves.
When can you use the inverse of sin?
You can use the inverse of sin when you want to solve an equation where x is the angle you're trying to find. Say sin(x)=32/50 Since you can't plug "x" into your calculator, use the arc sin (represented on your calculator by sin -1) on both sides to get rid of the sin. This is how it would plug into your calculator: sin-1 (32/50) Whatever the answer is would be what "x" equals.
How do you use the Pythagoras theorem in circle?
In a circle that has a radius of one you use Pythagorean theorem to derive the sine, cosine and tangent formulas. Draw a circle around the origin on graph paper. The sine is the line segment from the point where the side of the angle intersects down to the x-axis. etc.
How do you calculate the sine of 30 degrees?
Normally you would use one of the infinite series to calculate the sine of an angle. Fortunately, though, this has already been done and was published in mathematical tables. Nowadays, though, you would simply use a computer or calculator. Even more fortunately, sin(30 deg) = 1/2 so you don't even need a calculator.
How do you solve sin x equals constant?
Both the sine and the inverse sine (and similar trigonometric functions) are complicated to calculate. Therefore, you either look it up in a table, or use a scientific calculator. Some values, you should know by heart.Let's try an example: sin x = 0. This asks for the inverse sine, and you can have a calculator calculate it. But you should already know that the sine of 0 is zero, so that is one solution - incidentally, the solution which a calculator gives you if you ask for inverse sine, arc-sine, or something similar (you will usually have to press a special key before the sine function, to get the inverse sine - read the instructions for your calculator).But the sine of x is also equal to zero for an angle of 180 degrees, of 360 degrees, etc. - repeating every 180 degrees (or every pi radians).
How do you work out sin angles in trigonometry?
You could try the series sin(x) = 1 - x/1! + x^3/3! - x^5/5! + ... but you would soon need a calculator. And if you're using a calculator you may as well use it to find the sine.
What is the cosecant of a 63 degree angle?
Please do this kind of calculation on your scientific calculator. You can use the one that comes with Windows or whatever operating system you are using. The cosecant is the reciprocal of the sine, therefore, calculate 1 / sine(63).
What is the sine of 15 degrees in math?

What metric measure would you use to measure the length of a calculator?
A calculator would be between 100 and 150 millimetres.

How could you describe the sine function?
You may have to draw this to understand the Sine function for a right triangle (degree mode on a calculator).Draw a right triangle. Choose either angle (not the right angle, < div> C)) which will be referred to as < (AngleThe "Hypotenuse" is the longest side (IE. the side opposite
How would a person be able to use the Bra Size Calculator?
A person would be able to use the Bra Size Calculator online, by taking measurements of the bust line and other important measurements and plugging them into the calculator.
What would you use to measure the weight of a stone?
a calculator
What would be used to work out a calculation?
Most would use a calculator.
A wire from a post touches the ground at a point 6.3 meters from the post and if the the post and a wire form an angle of depression of 64 degrees so what is the length of the wire?
We need to use a little trigonometry to answere this. The sine of an angle in a right angled triangle is given by sine = opposite divided by hyponenuse that is the length of the side opposite the given angle divided by the length of the hypotenuse (or longest side). From that we can obtain that the length of the hypotenuse = opposite divided by sine. The sine is found by using a set of trigonometric tables or a scientific calculator (the majority of computers have a scientific calculator). The sine of 64 degrees is 0.89879, therefore the length of the wire (the hypotenuse) is 6.3 divided by 0.89879 which equals 7.009 metres.
