((x-1)/x)^'

(\frac{x - 1}{x})^{^{'}}

\frac{1}{x ^{2}}

Solution steps

(\frac{x - 1}{x})^{'}

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

(x - 1)^{'} = 1

x^{'} = 1

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

Simplify

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

= \frac{1}{x ^{2}}

\frac{d}{d x} (2 x cos (x) - x^{2} sin (x))

\frac{d}{d x} (lo g_{6} (5 x + 1))

\int_{0}^{1 - ∣ x - 1 ∣} 1 d y

\frac{d}{d x} (3 (x^{2} - 1)^{2})

\frac{\partial}{\partial x} (- cos^{2} (x))
