Sine of 225 degrees = - 0.5 sqrt(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 sine of an angle can never equal 2 because the sine function, defined as the ratio of the length of the opposite side to the hypotenuse in a right triangle, has a range of values between -1 and 1. This means that for any angle, the sine value will always fall within this interval, making it impossible for sine to equal 2. Therefore, there are no angles for which the sine function outputs a value of 2.

Sine(120) = sqrt(3/4) or sqrt(3)/2 = 0.866025
sqrt 2 / 2 is the answer.
Divide -900 by 360, and the remainder will be the angle you need to find the sine of: -900 / 360 = -2.5 --> -900 = 360*(-2 - 0.5), so sine(-180°) = sine(-900°). sine(-180°) = 0
