(\partial)/(\partial y)(yx^{y-1})

Lösung

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

x^{y - 1} + y x^{y - 1} ln (x)

Schritte zur Lösung

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

Behandle

x

als Konstante

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = y, g = x^{y - 1}

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

\frac{\partial}{\partial y} (y) = 1

\frac{\partial}{\partial y} (x^{y - 1}) = x^{y - 1} ln (x)

= 1 \cdot x^{y - 1} + x^{y - 1} ln (x) y

Vereinfache

= x^{y - 1} + y x^{y - 1} ln (x)

y^{^{''}} + 6 y^{^{'}} + 58 y = 0

\frac{d}{d x} (\frac{- x ^{2}}{8})
