(\partial ^2)/(\partial x\partial y)(xye^{-6y})

Lösung

\frac{\partial ^{2}}{\partial x \partial y} (x y e^{- 6 y})

- 6 e^{- 6 y} y + e^{- 6 y}

Schritte zur Lösung

\frac{\partial ^{2}}{\partial x \partial y} (x y e^{- 6 y})

\frac{\partial}{\partial x} (x y e^{- 6 y}) = e^{- 6 y} y

= \frac{\partial}{\partial y} (e^{- 6 y} y)

\frac{\partial}{\partial y} (e^{- 6 y} y) = - 6 e^{- 6 y} y + e^{- 6 y}

= - 6 e^{- 6 y} y + e^{- 6 y}
