\frac{d}{d x} (x - \frac{1}{3} x^{3})

1 - x^{2}

Solution steps

\frac{d}{d x} (x - \frac{1}{3} x^{3})

Simplify

x - \frac{1}{3} x^{3} : x - \frac{x ^{3}}{3}

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

Apply the Sum/Difference Rule:

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

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

\frac{d x}{d x} = 1

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

= 1 - x^{2}

\int \frac{x}{x + 10} d x

\int_{0}^{x} \frac{e ^{t^{2}} - 1}{t} d t

n = 1 \sum \infty \frac{n ^{5}}{3 ^{n}}

\int sec (x) (tan (x) + cos (x)) d x

3 y^{^{'}} = \frac{3 x \cdot y + 18 x ^{2} + 2 y ^{2}}{x ^{2}}, y (1) = 3
