(sin−1 x) Read as the inverse of sine x, sin −1 x is the measure of the angle with sine x. We can also write y = arcsin x.Note that the notation refers to the inverse of the sine function, not .Because y = sin −1 x is equivalent to x = sin y and there are infinitely many angles y such that sin y = x, the inverse function is restricted to select the principal value of y such that .
