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
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.
Sin30 degrees is 0.50000
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.
sine 45 = 0.850903525
1 it can not used when the angle more than 45 degrees.....
√ 1/2 = sine(45)= cosine(45) -Key
