derivative of

y = x - x^{3}

1 - 3 x^{2}

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

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

= 1 - 3 x^{2}

\int e^{- 2 \cdot π \cdot x} \cdot cos (π \cdot x) d x

n = 1 \sum \infty \frac{1}{4 n ^{4}}

\int \frac{x ^{2} - 5}{( x + 1 ) ^{3}} d x

\int_{0}^{π} 20 sin^{4} (x) d x

\frac{d y}{d t} + e^{t} y = 8 e^{t}
