It represents the inverse of the sine function. Recall f(x) and f-1(x). sin-1x means the same as arcsin x, i.e., the arc whose sine is x.

What is arcsin equivalent to?

Arcsine is the inverse of sine function. It is used to evaluate the angle whose sine value is equal to the ratio of its opposite side and hypotenuse. Therefore, if we know the length of opposite side and hypotenuse, then we can find the measure of angle.

Is arcsin same as cosec?

What’s difference between Arcsin and Cosec? Yes arcsin is inverse of sin but cosec is 1/sin, which looks like and inverse aswell.

The Asin function returns the arcsine, or inverse sine, of its argument. The arcsine is the angle whose sine is the argument. The returned angle is given in radians in the range -π/2 to π/2.
