derivative of

- \frac{n ( - 1 ) ^{n}}{n + 1}

Undefined

Solution steps

\frac{d}{d n} (- \frac{n ( - 1 ) ^{n}}{n + 1})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - \frac{d}{d n} (\frac{n ( - 1 ) ^{n}}{n + 1})

Apply the Quotient Rule:

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

= - \frac{\frac{d}{d n} ( n ( - 1 ) ^{n} ) ( n + 1 ) - \frac{d}{d n} ( n + 1 ) n ( - 1 ) ^{n}}{( n + 1 ) ^{2}}

\frac{d}{d n} (n (- 1)^{n}) =

Undefined

= Undefined
