(sqrt 2) / 2
The sine of 75 degrees is about 0.9659
sine 40° = 0.642788
Sine(30) = 0.5 or 1/2
Sin(-225) = 0.7071 ... = 1/sqrt(2) = sqrt(2) / 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.
Sine of 225 degrees = - 0.5 sqrt(2)
225 degrees
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 .
The sine of 22.5 degrees is 0.383
sine-1(0.3420201433) = 20 degrees
sin77 = 0.974 Therefore the sine of 77 degrees is 0.974
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
sine 40° = 0.642788
sine(15 degrees) = 0.25882 (rounded)
Sine(30) = 0.5 or 1/2
225 degrees Celsius is equal to 437 degrees Fahrenheit.
