(\partial)/(\partial y)(sqrt(4-x^2-5y^2))

Lösung

\frac{\partial}{\partial y} (4 - x^{2} - 5 y^{2})

- \frac{5 y}{4 - x ^{2} - 5 y ^{2}}

Schritte zur Lösung

Behandle

x

als Konstante

Wende die Kettenregel an:

\frac{1}{2 4 - x ^{2} - 5 y ^{2}} \frac{\partial}{\partial y} (4 - x^{2} - 5 y^{2})

= \frac{1}{2 4 - x ^{2} - 5 y ^{2}} \frac{\partial}{\partial y} (4 - x^{2} - 5 y^{2})

\frac{\partial}{\partial y} (4 - x^{2} - 5 y^{2}) = - 10 y

= \frac{1}{2 4 - x ^{2} - 5 y ^{2}} (- 10 y)

Vereinfache

\frac{1}{2 4 - x ^{2} - 5 y ^{2}} (- 10 y) : - \frac{5 y}{4 - x ^{2} - 5 y ^{2}}

= - \frac{5 y}{4 - x ^{2} - 5 y ^{2}}
