(\partial)/(\partial y)(sqrt(xye^y))

Lösung

\frac{\partial}{\partial y} (x y e^{y})

\frac{e ^{y} x ( 1 + y )}{2 y e ^{y}}

Schritte zur Lösung

\frac{\partial}{\partial y} (x y e^{y})

Behandle

x

als Konstante

Wende die Kettenregel an:

\frac{1}{2 x y e ^{y}} \frac{\partial}{\partial y} (x y e^{y})

= \frac{1}{2 x y e ^{y}} \frac{\partial}{\partial y} (x y e^{y})

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

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

Vereinfache

\frac{1}{2 x y e ^{y}} x (e^{y} + e^{y} y) : \frac{e ^{y} x ( 1 + y )}{2 y e ^{y}}

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

\int \frac{2 y}{1 - y ^{2}} d y

d er i v a t i v e g (x) = x e^{x}

\int \frac{4}{x ^{2}} - \frac{7}{x ^{5}} d x

t an g e n t f (x) = x^{3} + 7 x - 7, (1, 1)
