\frac{d}{d x} (\frac{x ^{9}}{9} - \frac{x ^{7}}{7})

x^{8} - x^{6}

Solution steps

\frac{d}{d x} (\frac{x ^{9}}{9} - \frac{x ^{7}}{7})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (\frac{x ^{9}}{9}) - \frac{d}{d x} (\frac{x ^{7}}{7})

\frac{d}{d x} (\frac{x ^{9}}{9}) = x^{8}

\frac{d}{d x} (\frac{x ^{7}}{7}) = x^{6}

= x^{8} - x^{6}

x \to 1 lim (\frac{e ^{x^{2} - 1}}{x ^{2} - 3 x + 2})

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