Question

THE FUNCTION ARCSINE CAN ALSO BE DEFINED AS?

Answer 1

The arcsine,
`\sin^(-1)`, is the inverse of the
`\sin` function. This means that it takes as inputs what would usually be outputs for the
`\sin` function and produces as outputs what would usually be inputs for the
`\sin` function.

This can be particularly useful when you're trying to find an angle on a right triangle, but you've only been given the lengths of the sides. To find any angle
`\theta` in a right triangle, just take
`\sin^(-1) (o)/(h)`, where o is the side opposite
`\theta` and h is the hypotenuse of the right triangle.
