integral from 1/x to x of (x^2)/(y^2)

Lösung

\int_{\frac{1}{x}}^{x} \frac{x ^{2}}{y ^{2}} d y

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

Schritte zur Lösung

\int_{\frac{1}{x}}^{x} \frac{x ^{2}}{y ^{2}} d y

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= x^{2} \cdot \int_{\frac{1}{x}}^{x} \frac{1}{y ^{2}} d y

Wende die Potenzregel an

= x^{2} [- \frac{1}{y}]_{\frac{1}{x}}^{x}

Berechne die Grenzen:

- \frac{1}{x} + x

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

\int_{0}^{2} x^{3} + 1 d x

\int_{100}^{200} 0.1 e^{- 0.002 x} d x

\int_{1}^{6} \frac{ln ( x )}{x} d x

\int_{0}^{2} y^{2} sin (π y^{3}) d y

\int_{0.1}^{0.2} \frac{1}{x ^{2}} d x
