one over root of 2 or (1/square root of 2) or 1/1.414213562 or 0.707106781
The sine of 75 degrees is about 0.9659
0.70710678118654752440084436210485 ----------------------- Improve: If you mean 45 degrees then it equals: Sqrt (2) /2 (which is the exact form of the above approximate form)
sine 40° = 0.642788
Sine(30) = 0.5 or 1/2
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.
The arc-sine (or inverse sine) of 45 degrees is the angle whose sine value is equal to the sine of 45 degrees. Since the sine of 45 degrees is ( \frac{\sqrt{2}}{2} ), the arc-sine of ( \frac{\sqrt{2}}{2} ) is 45 degrees. Therefore, the arc-sin of 45 degrees is also 45 degrees, given that it falls within the principal range of the inverse sine function.
By shifting the sine wave by 45 degrees.
You mean, "N in 45 degrees"? Ans. sine(45) = 0.7071 N
sin-1(0.707) = 44.99134834 or about 45 degrees
The square root of two over two.
The sine of 45 degrees is equal to (\frac{\sqrt{2}}{2}). This value arises from the properties of a 45-45-90 triangle, where both legs are equal and the hypotenuse is (\sqrt{2}) times the length of each leg. Consequently, the sine function, which is defined as the ratio of the opposite side to the hypotenuse, yields this result for 45 degrees.
sine 45 = 0.850903525
1 it can not used when the angle more than 45 degrees.....
√ 1/2 = sine(45)= cosine(45) -Key
The sine of 75 degrees is about 0.9659
It's not. The sine of 32 degrees is approximately 0.53. The sine of 59 degrees is approximately 0.86. For a definition of sine, see: http://en.wikipedia.org/wiki/Trigonometric_function .
