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

\frac{- x sin ( x ) - cos ( x ) + 1}{x ^{2}}

Solution steps

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

Apply the Quotient Rule:

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

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

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

\frac{d x}{d x} = 1

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

Simplify

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

= \frac{- x sin ( x ) - cos ( x ) + 1}{x ^{2}}

y^{^{''}} - 12 y + 36 y = 0

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

\int_{1}^{3} \frac{5}{x ^{2} + 2 x + 1} d x

f (x) = ln (5 - x)

\frac{d}{d x} (ln (x + y + 5))
