sin x = (e ix - e-ix) / 2i: Inverse sine function. The arcsine of x is defined as the inverse sine function of x when -1≤x≤1. When the sine of y is equal to x: sin y = x. Then the arcsine of x is equal to the inverse sine function of x, which is equal to y: arcsin x = sin-1 (x) = y. See: Arcsin function.
