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

\frac{4}{x ^{3}}

Solution steps

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

Apply the Sum/Difference Rule:

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

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

\frac{d}{d x} (1) = 0

\frac{d}{d x} (\frac{2}{x ^{2}}) = - \frac{4}{x ^{3}}

= 0 - (- \frac{4}{x ^{3}})

Simplify

= \frac{4}{x ^{3}}

\int x^{100} + x^{99} d x

(x^{2} - y^{2}) d x + 2 x y d y = 0

\int_{0}^{1} t^{3} (3 + t^{4})^{3} d t

f (x) = 12 - x

t \to 0 lim (\frac{sin ( 3 t )}{t})
