Sin−1(x), Arcsin Definition:

Definition of Arcsin provided by wikipedia:

arcsin (trigonometry), the inverse trigonometric function of sine.

In mathematics, the inverse trigonometric functions (occasionally called cyclometric functions[1]) are the inverse functions of the trigonometric functions (with suitably restricted domains). Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle’s trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.

The arcsine of x is defined as the inverse trigonometric function of sin when -1≤x≤1.

When :

sin y = x.

Then the arcsin of x is equal to the inverse sin trigonometric  function of x, which is equal to y:

arcsin x = sin-1 x = y.
