$F^{- 1} = cos (\frac{x}{2})$ $F^(-1)=cos(x/2)$

Explanation:

The inverse function $f^{- 1} (x)$ $f^(-1)(x)$ is a reflection of the function $f (x)$ $f(x)$ along the curve $y = x$ $y=x$ . In other words, switching $x$ $x$ and $y$ $y$ around.

$F (x) = 2 arccos x$ $F(x)=2arccosx$
Let $y = F (x)$ $y=F(x)$

$y = 2 arccos x$ $y=2arccosx$
$x = cos (\frac{y}{2})$ $x=cos(y/2)$
$F^{- 1} = cos (\frac{x}{2})$ $F^(-1)=cos(x/2)$
