Sin30 degrees is 0.50000
The exact value is 0.5*sqrt(3)
The sine of 75 degrees is about 0.9659
sine 40° = 0.642788
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 30 degrees
sine(15 degrees) = 0.25882 (rounded)

The Sine of 216 degrees = -0.587785252 The Cosine of 216 degrees = -0.909016994
0.524 or pi/6
It is 0.1734
The sine of 20° is approximately 0.342.
The sine of 180 degrees is 0. Remember, the sine value on a unit circle is the y-value. If you find f(pi) in the function f(x)=sin(x), you will get zero as an answer.
sin-1(0.707) = 44.99134834 or about 45 degrees
