cos(30) / sin(45) = [sqrt(3)/2] / [sqrt(2)/2] =
[sqrt(3)/2] x [2/sqrt(2)] = sqrt(3)/sqrt(2) =
sqrt(1.5) = about 1.2247 (rounded)
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
You are referring to a special case of shape its called a line
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
3060 degrees is eight and a half revolutions. So the sine of 3060 degrees is the same as the sine of 180 degrees (half a revolution) sin 180 = 0
The arc-sine (or inverse sine) of 45 degrees is the angle whose sine value is equal to the sine of 45 degrees. Since the sine of 45 degrees is ( \frac{\sqrt{2}}{2} ), the arc-sine of ( \frac{\sqrt{2}}{2} ) is 45 degrees. Therefore, the arc-sin of 45 degrees is also 45 degrees, given that it falls within the principal range of the inverse sine function.

On a sine wave, the voltage is equal to zero at every integer multiple of 180 degrees. This occurs at 0 degrees, 180 degrees, 360 degrees, and so on. These points represent the crossings of the waveform along the horizontal axis, where the sine function equals zero.
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
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
A way of remembering how to compute the sine, cosine, and tangent of an angle. SOH stands for Sine equals Opposite over Hypotenuse. CAH stands for Cosine equals Adjacent over Hypotenuse. TOA stands for Tangent equals Opposite over Adjacent.
3060 degrees is eight and a half revolutions. So the sine of 3060 degrees is the same as the sine of 180 degrees (half a revolution) sin 180 = 0
The square root of two over two.
