limit as x approaches 3-of (x^2)/(x-3)

Lösung

x \to 3 - lim (\frac{x ^{2}}{x - 3})

- \infty

Schritte zur Lösung

x \to 3 - lim (\frac{x ^{2}}{x - 3})

\frac{x ^{2}}{x - 3} = x^{2} \frac{1}{x - 3}

= x \to 3 - lim (x^{2} \frac{1}{x - 3})

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

mit Einschränkung des unbestimmten Ausdrucks

= x \to 3 - lim (x^{2}) \cdot x \to 3 - lim (\frac{1}{x - 3})

x \to 3 - lim (x^{2}) = 9

x \to 3 - lim (\frac{1}{x - 3}) = - \infty

= 9 (- \infty)

Wende die Unendlichkeitseigenschaft an:

c \cdot (- \infty) = - \infty

= - \infty

\int e^{(a - s) x} d x

\int \frac{6 x ^{2} + 2 x - 1}{3 x ^{2}} d x

\frac{d}{d x} (\frac{y}{x ^{2} + y ^{2} + 1})

\frac{d}{d x} (ln (x) sec (x))

\frac{d y}{d x} = 3 x^{2} - x y
