## Anwendung der Integralrechnung
|
||||||
|
### Der Mittelwert
|
||||||
|
Der Mittelwert einer Funktion errechnet sich mit der folgenden Formel:
|
||||||
|
|
||||||
|
$$\mu = \frac{1}{b - a} \cdot \int_a^b{f(x)}dx$$
|
||||||
|
|
||||||
|
### Die Arbeit
|
||||||
|
$$\int_{s_1}^{s_2}{F(s)}ds$$
|
||||||
|
|
||||||
|
### Rotationskörper
|
||||||
|
#### Rotationskörper um die $x$-Achse
|
||||||
|
$$V = \pi \cdot \int_a^b{(f(x))^2}dx$$
|
||||||
|
|
||||||
|
#### Rotationskörper um die $y$-Achse
|
||||||
|
$$V = \pi \cdot \int_c^d{(g(y))^2}dy$$
|
||||||
|
|
||||||
|
#### Mantelfläche eines Rotationskörpers
|
||||||
|
$$M = 2 \cdot \pi \cdot \int_a^b{y \cdot \sqrt{1 + (y')^2}}dx$$
|
||||||
|
|
||||||
|
### Bogenlänge einer Kurve
|
||||||
|
$$s = \int_a^b{\sqrt{1 + (y')^2}}dx$$
|
||||||
|
|
||||||
|
### Schwerpunkt
|
||||||
|
$$x_S = \frac{1}{A} \cdot \int_a^b{x \cdot (f_o(x) - f_u(x))}dx$$
|
||||||
|
$$y_S = \frac{1}{2A} \cdot \int_a^b{(f_o^2(x) - f_u^2(x))}dx$$
|
||||||
|
|
||||||
|
### Schwerpunkt eines Rotationskörpers
|
||||||
|
$$x_S = \frac{\pi}{V} \cdot \int_a^b{x \cdot f^2(x)}dx$$
|
||||||
|
$$y_S = 0$$
|
||||||
|
$$z_S = 0$$
