The sine of 75 degrees is about 0.9659
arcsin(.75)≈0.848062079
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 cosecant of an angle is the reciprocal of the sine of that angle. So, to find the cosecant of 105 degrees, you first need to find the sine of 105 degrees. The sine of 105 degrees is approximately 0.9659. Therefore, the cosecant of 105 degrees is approximately 1.0353 (1 divided by 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
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
sin77 = 0.974 Therefore the sine of 77 degrees is 0.974
sine 40° = 0.642788
sine(15 degrees) = 0.25882 (rounded)
Sine(30) = 0.5 or 1/2
Sine of 225 degrees = - 0.5 sqrt(2)
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.
