sin(pi/7) = 0.43388 (to 5 decimal places)
You can calculate that on any scientific calculator. Make sure you put it into the correct angle mode (degrees, or radians, depending on what you need), and press something like "inverse", followed by "sin".In Excel, you can type: =asin(0.58333) That will give you the angle in radians.
You can calculate the sine function on any scientific calculator, including the one included in Windows or other computers. Just make sure you select the correct type of angle measurement - degrees or radians, depending which you want to calculate.
Sin or Sine is the ratio of the Opposite side Over The Hypoteneuse of any right angled triangle inverse sin or inverse sine ( they mean the same thing ) uses the same ratio to find an unknown angle and can be written as sin-1 so if you know two sides ( opposite and Hypoteneuse ) then you can work out the sin...then you can either use a calculator to determine the inverse ( or angle ) or you could look up the sin in a booklet of sin values and determine the angle Example : in the triangle ABC the line ab=4 ac = 5 and the angle abc =90 we could find the sin of the angle acb sinacb= opp/hyp = 4/5 = 0.8 to find sin-1 of 0.8 calcultor press 0.8 press inv button or on newer calculators the 2nd functon button then press the button marked sin the display should then display 53.1301....or 53 to 2 sig figures
YES!!!! Sin(2x) = Sin(x+x') Sin(x+x') = SinxCosx' + CosxSinx' I have put a 'dash' on an 'x' only to show its position in the identity. Both x & x' carry the same value. Hence SinxCosx' + CosxSinx' = Sinx Cos x + Sinx'Cosx => 2SinxCosx
The sine of 33 degrees is approximately 0.5446.

How to calculate sin10 deg
33/36 x 100 = 91.67% To calculate a percentage, all you need to do is: x/y x 100 easy!
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
sin (theta) = [13* sin (32o)]/8 = 13*0.529919264/8 = 0.861118804 [theta] = sin-1 (0.861118804) [theta] = 59.44o
You can use the L'hopital's rule to calculate the limit of e5x -1 divided by sin x as x approaches 0.
cos(phi - 1) = cos(phi)cos(1) + sin(phi)sin(1)
The calculators have been programmed in such a way that they are able to calculate sin, cos and tan without the side lengths.
