Question

How do you find the value of `sin arcsin(-0.2)`?

Answer 1

The definition of
`arcsin(k)` is the value `m` such that `sin(m) = k`

So
`arcsin(-0.2)` is the value, `m`, for which `sin(m) = (-0.2)`

So `sin (arcsin(-0.2))`
is `sin(` the value for which `sin = (-0.2)` `)`

`sin(arcsin(-0.2)) = -0.2`
