\frac{d}{d x} (1 - ∣ x ∣)

- \frac{x}{∣ x ∣}

Solution steps

\frac{d}{d x} (1 - ∣ x ∣)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (1) - \frac{d}{d x} (∣ x ∣)

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

\frac{d}{d x} (∣ x ∣) = \frac{x}{∣ x ∣}

= 0 - \frac{x}{∣ x ∣}

Simplify

= - \frac{x}{∣ x ∣}

\int e^{x} + cos (x) d x

\int \frac{5 x + 3}{7 x - 1} d x

\frac{y}{5}

\frac{d ^{2}}{d x ^{2}} (12 x^{3} - 32 x^{2})

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