derivative of (cot(x)/x)

Solution

\frac{d}{d x} (\frac{cot ( x )}{x})

Solution

\frac{- x csc ^{2} ( x ) - cot ( x )}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{cot ( x )}{x})

Apply the Quotient Rule:

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

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

\frac{d}{d x} (cot (x)) = - csc^{2} (x)

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

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

Simplify

= \frac{- x csc ^{2} ( x ) - cot ( x )}{x ^{2}}
