2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
The answer depends on x, on whether x is measured in degrees or radians and on whether the question is about sin(x) + 2 or sin(x + 2).

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.
The answer will depend on x, and whether x is measured in degrees or radians.
Sin theta of 30 degrees is1/2
The sine of 120 degrees can be found using the unit circle. It is equivalent to sin(180° - 60°), which gives sin(120°) = sin(60°). Since sin(60°) is √3/2, the ratio for sin 120 degrees is √3/2.
sin(360+30) =sin(30)= 1/2
sin(1,305) = sin(225) = -0.70711 (rounded) = 1/2 of the negative square root of 2.

The sine of 210 degrees is equal to -1/2. This value can be derived from the unit circle, where 210 degrees is in the third quadrant, where sine values are negative. Specifically, sin(210°) corresponds to sin(210° - 180°) = sin(30°), and since sine is negative in the third quadrant, sin(210°) = -sin(30°) = -1/2.
