Schritte zur Lösung

x \to 4 lim (\frac{∣ x ∣ - 4}{x - 4})

x

ist positiv wenn

x \to 4

. Deshalb

∣ x ∣ = x

= x \to 4 lim (\frac{x - 4}{x - 4})

Vereinfache

= x \to 4 lim (1)

x \to a lim c = c

= 1

\frac{\partial}{\partial z} (x e^{- y} - z)

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

d er i v a t i v e \frac{s - 2}{s + 4}
