integral from y^2 to 8-2x^2-y^2 of 10xz

Lösung

\int_{y^{2}}^{8 - 2 x^{2} - y^{2}} 10 x z d z

20 x (x^{4} + x^{2} y^{2} - 8 x^{2} + 16 - 4 y^{2})

Schritte zur Lösung

\int_{y^{2}}^{8 - 2 x^{2} - y^{2}} 10 x z d z

Entferne die Konstante:

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

= 10 x \cdot \int_{y^{2}}^{8 - y^{2} - 2 x^{2}} z d z

Wende die Potenzregel an

= 10 x [\frac{z ^{2}}{2}]_{y^{2}}^{8 - y^{2} - 2 x^{2}}

Berechne die Grenzen:

\frac{( 8 - y ^{2} - 2 x ^{2} ) ^{2}}{2} - \frac{y ^{4}}{2}

= 10 x (\frac{( 8 - y ^{2} - 2 x ^{2} ) ^{2}}{2} - \frac{y ^{4}}{2})

Vereinfache

= 20 x (x^{4} + x^{2} y^{2} - 8 x^{2} + 16 - 4 y^{2})

\int_{0}^{2} \frac{e ^{x}}{10 + e ^{x}} d x

\int_{0}^{π} θ sin (θ) d θ

\int_{0}^{x} cos (y) d y
