limit as x approaches 2+of (x^2+1)/(x-2)

Lösung

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

\infty

Schritte zur Lösung

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

\frac{x ^{2} + 1}{x - 2} = (x^{2} + 1) \frac{1}{x - 2}

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

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

x \to 2 + lim (x^{2} + 1) = 5

x \to 2 + lim (\frac{1}{x - 2}) = \infty

= 5 \cdot \infty

Wende die Unendlichkeitseigenschaft an:

c \cdot \infty = \infty

= \infty

\int_{1}^{\infty} e^{- 11 x} d x

d er i v a t i v e y = e^{- x} ln (x)

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

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

\frac{\partial}{\partial x} (ln (x - 6 y))
