derivative of

\frac{x}{9} - \frac{9}{x}

\frac{1}{9} + \frac{9}{x ^{2}}

Solution steps

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

Apply the Sum/Difference Rule:

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

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

\frac{d}{d x} (\frac{x}{9}) = \frac{1}{9}

\frac{d}{d x} (\frac{9}{x}) = - \frac{9}{x ^{2}}

= \frac{1}{9} - (- \frac{9}{x ^{2}})

Simplify

= \frac{1}{9} + \frac{9}{x ^{2}}

f (x) = e^{c o s (x)}

x^{2} + 2 y^{2} = 3, (1, 1)

\int (5 - 4 e^{x} + \frac{3}{x ^{2}}) d x

h \to 0 lim (\frac{( 2 h ^{2} + 6 h )}{h})

x \to 0 lim (f (x) \cdot g (x))
