(\partial)/(\partial x)((x)(x^2+y^2))

Lösung

\frac{\partial}{\partial x} ((x) (x^{2} + y^{2}))

3 x^{2} + y^{2}

Schritte zur Lösung

\frac{\partial}{\partial x} ((x) (x^{2} + y^{2}))

Behandle

y

als Konstante

Wende die Produktregel an:

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

f = x, g = x^{2} + y^{2}

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

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

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

= 1 \cdot (x^{2} + y^{2}) + 2 xx

Vereinfache

1 \cdot (x^{2} + y^{2}) + 2 xx : 3 x^{2} + y^{2}

= 3 x^{2} + y^{2}
