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.
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 .!
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.
Yes, because all sound waves can be modelled as sine (or cosine) waves, or combinations of sine waves.
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.
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.
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.
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).
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.
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).
sin(15)_=_0.65028784">sin(15) = 0.65028784in the future, use a calculatoralso, you should know that its sinfinally, you should know that i just typed in 'sin 15' in Google, because Google has a terrific calculator built in-----------------------------------------Small problem: When you type sin(15) into Google Calculator, you get the sine of 15 radians.15 radians = 859.436693 degreesTo answer the actual question that was asked try sine (15 degrees) orsin(15 degrees).sine(15 degrees) = 0.258819045
A calculator would be between 100 and 150 millimetres.

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.
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

Most would use a calculator.
I couldn't tell you because it is pretty simple stuff so for me it would be a non calculator topic. For younger kids however I would use a scientific calculator to help them understand.
