Question

How do you find the exact value of `sin(sin^-1(0.3))`?

Answer 1

`0.3`

Explanation:

Any value you get for `sin^(-1)(0.3)` would be changed back to `0.3` when you take the sin of it.

This is because `y=sin^(-1)x-=x=siny`, doing `sin(sin^(-1)(x))` works in the exact same way as `ln(e^x)` or `e^ln(x)`.
