fläche y= 3/x ,y=12x,y= 1/(12x)

Lösung

fläche

y = \frac{3}{x}, y = 12 x, y = \frac{1}{12 x}

Lösung

- \frac{35}{12} + 6 ln (6) + divergiert

Schritte zur Lösung

Um die Schnittpunkte zu finden, löse

f_{i} (x) = f_{j} (x)

\frac{3}{x} = 12 x : x = \frac{1}{2}, x = - \frac{1}{2}

\frac{3}{x} = \frac{1}{12 x} :

Keine Lösung für

x \in R

12 x = \frac{1}{12 x} : x = \frac{1}{12}, x = - \frac{1}{12}

= \int_{- \frac{1}{2}}^{- \frac{1}{12}} ∣ f_{1} (x) - f_{2} (x) ∣ d x + \int_{- \frac{1}{12}}^{\frac{1}{12}} ∣ f_{1} (x) - f_{3} (x) ∣ d x + \int_{\frac{1}{12}}^{\frac{1}{2}} ∣ f_{2} (x) - f_{1} (x) ∣ d x

= \int_{- \frac{1}{2}}^{- \frac{1}{12}} \frac{3}{x} - 12 x d x + \int_{- \frac{1}{12}}^{\frac{1}{12}} \frac{3}{x} - \frac{1}{12 x} d x + \int_{\frac{1}{12}}^{\frac{1}{2}} 12 x - \frac{3}{x} d x

\int_{- \frac{1}{2}}^{- \frac{1}{12}} \frac{3}{x} - 12 x d x = 3 ln (6) - \frac{35}{24}

\int_{- \frac{1}{12}}^{\frac{1}{12}} \frac{3}{x} - \frac{1}{12 x} d x =

divergiert

\int_{\frac{1}{12}}^{\frac{1}{2}} 12 x - \frac{3}{x} d x = - \frac{35}{24} + 3 ln (6)

= 3 ln (6) - \frac{35}{24} + divergiert - \frac{35}{24} + 3 ln (6)

Vereinfache

= - \frac{35}{12} + 6 ln (6) + divergiert
