Určete první derivaci funkce \(f\colon y =\ln \left (\frac{1+x}
{1-x}\right )\).
\(f^{\prime}(x) = \frac{2}
{1-x^{2}} ;\ x\in \left (-1;1\right )\)
\(f^{\prime}(x) = \frac{2}
{1-x^{2}} ;\ x\in \mathbb{R}\setminus \left \{-1;1\right \}\)
\(f^{\prime}(x) = \frac{1-x}
{1+x};\ x\in \left (-1;1\right )\)
\(f^{\prime}(x) = \frac{1-x}
{1+x};\ x\in \mathbb{R}\setminus \left \{-1;1\right \}\)
