limit as x approaches 0-of (2x)/(|x|)

Lösung

x \to 0 - lim (\frac{2 x}{∣ x ∣})

- 2

Schritte zur Lösung

x \to 0 - lim (\frac{2 x}{∣ x ∣})

x

ist negativ wenn

x \to 0 -

. Deshalb

∣ x ∣ = - x

= x \to 0 - lim (\frac{2 x}{- x})

\frac{2 x}{- x} = - 2

= x \to 0 - lim (- 2)

x \to a lim c = c

= - 2

t y^{^{''}} - y^{^{'}} = t^{2} + t, y (1) = 1, y^{^{'}} (1) = 5

s l o p e (3, - 7), (10, - 4)

\frac{d}{d x} (3 8 x^{7} + 9 x^{6})

\int \frac{1}{x ^{2} - 4 x + 4} d x

x \to 9 - lim (\frac{6 x}{x - 9})
