It is an abbreviation for sine, and that word together with cosine and tangent are used in simple trigonometrical calculations about right-angled triangles. If we take the shortest side of the triangle, together with the hypotenuse (the longest side) these two sides enclose an angle. The sine of that angle tells us how long the third side is compared with the hypotenuse. Draw a triangle ABC with the right angle at A, the shortest side called AB, the hypotenuse called BC, and the remaining side CA, then if we wanted the sine of angle B we would divide the length of CA by the length of CB. If you want to find the Sine of 50 degrees on a calculator you would press buttons in this order: 50, then the sin button, and the answer would be given almost instantly in the calculator's window. That's much quicker than having to calculate for yourself.

What is sin 7?

How do you put sin on a calculator?
You need a scientific calculator, or one with function keys.
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 calculate sin20?
Sin(20) = You need either a scientific calculator or Castles four figure Tables. Using a scientific calculator Sin ( 20 ) = 0.342020143.... Sin(20) ~ 0.3420 (4d.p.).
How do I find Sin A .42 is A is an acute angle. And how do i enter that on a calculator?
If sin(A) = 0.42 then A = arcsin(0.42).On calculators, the arcsin key is usually reached by using another key before the sin key, and is shown as "sin to the power -1".Make sure that your calculator is set to degrees rather than radians (to check this, try sin(90). If the answer is 1 the calculator is in degree mode; if it is 0.8940 it is in radian mode.
How do you use sin theta in a calculator?
To use sin(theta) on a calculator, first ensure that your calculator is set to the correct mode (degrees or radians) depending on the angle measurement you are working with. Enter the angle value (theta) and then press the "sin" button to obtain the sine value. For example, if you want to find sin(30°), you would input 30, switch to sine mode, and then press "sin" to get the result, which is 0.5.
How do you calculate the angle if you know Sin of the angle?
Use the inverse/2nd function button on your calculator. e.g. Sin(angle) = 0.5 Then angle = Sin^(-1) 0.5 or ArcSin 0.5. On your calculator make sure you are in DEGREE Mode. Over the 'Sin' button there should be the symbol 'Sin^-1)' So press ' Inver/2nd function/shift' as the case maybe for your calculator Then 'Sin' '0.5' '=' Answer should be '30' Degrees. Similarly for any angle and the two other trig functions (Cos) & (Tan).
What does sin stand for on a calulator?
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
