To calculate the Arcsin:
\[ \text{Arcsin}(x) = \sin^{-1}(x) \]
Where:
Arcsin, or inverse sine, is the function that returns the angle whose sine is the given number. It is the inverse operation of the sine function and is used to find the angle when the sine of the angle is known. Arcsin is defined for values between -1 and 1, as these are the range limits of the sine function.
Let's assume the following value:
Using the formula:
\[ \text{Arcsin}(0.5) = \sin^{-1}(0.5) \approx 30^\circ \]
The Arcsin of 0.5 is approximately 30°.
