derivative of

- \frac{7}{x ^{2}}

\frac{14}{x ^{3}}

Solution steps

\frac{d}{d x} (- \frac{7}{x ^{2}})

Take the constant out:

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

= - 7 \frac{d}{d x} (\frac{1}{x ^{2}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= - 7 \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

= - 7 (- 2 x^{- 2 - 1})

Simplify

- 7 (- 2 x^{- 2 - 1}) : \frac{14}{x ^{3}}

= \frac{14}{x ^{3}}

y = 8 - x^{2}, y = x^{2}, x = - 3, x = 3

(x^{2} + 4) d y = (2 x - 8 x y) d x

\int - \frac{2}{πn} cos (\frac{πn}{2} x) d x

\frac{d y}{d x} = \frac{7 x ^{2}}{5 y ^{2}}

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