derivative of ln(sqrt(x(1-x)))

Solution

\frac{d}{d x} (ln (x (1 - x)))

Solution

\frac{1 - 2 x}{2 x ( 1 - x )}

Solution steps

\frac{d}{d x} (ln (x (1 - x)))

Apply the chain rule:

\frac{1}{x ( 1 - x )} \frac{d}{d x} (x (1 - x))

= \frac{1}{x ( 1 - x )} \frac{d}{d x} (x (1 - x))

\frac{d}{d x} (x (1 - x)) = \frac{1 - 2 x}{2 x ( 1 - x )}

= \frac{1}{x ( 1 - x )} \cdot \frac{1 - 2 x}{2 x ( 1 - x )}

Simplify

\frac{1}{x ( 1 - x )} \cdot \frac{1 - 2 x}{2 x ( 1 - x )} : \frac{1 - 2 x}{2 x ( 1 - x )}

= \frac{1 - 2 x}{2 x ( 1 - x )}
