Given function is
$y (x) = x \tanh^{- 1} (x) + \ln (\sqrt{1 - x^{2}})$
we have to difference the function.
So taking differentiation on both sides, we get
$y^{'} (x) = \frac{d}{d x} [x \tanh^{- 1} (x) + \ln (\sqrt{1 - x})]$
$= \frac{d}{d x} [x \tanh^{- 1} (x)] + \frac{1}{2} \frac{d}{d x} [\ln (1 - x^{2})]$
$= \tanh^{- 1} (x) + x \cdot \frac{d}{d x} [\tanh^{- 1} (x)] + \frac{1}{2} \frac{- 2 x}{(1 - x^{2})}$
$= \tanh^{- 1} (x) + \frac{x}{1 - x^{2}} - \frac{x}{1 - x^{2}}$
$= \tanh^{- 1} (x)$
Therefore $y^{'} (x) = \tanh^{- 1} (x)$
