Sine of 225 degrees = - 0.5 sqrt(2)
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
Yes, the sine function is a periodic function. It has a period of 2 pi radians or 360 degrees.
sine(15 degrees) = 0.25882 (rounded)
1.11842 sine 34°= 2 * sine 34°= 2 * 0.55919= 1.1184
Sine of 225 degrees = - 0.5 sqrt(2)
(sqrt 2) / 2
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 .
sine-1(0.3420201433) = 20 degrees
The sine of 22.5 degrees is 0.383
sin(30) = 0.5
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
sin77 = 0.974 Therefore the sine of 77 degrees is 0.974
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
