(\partial)/(\partial y)(2xy^4e^y+2xy^3+y)

Lösung

\frac{\partial}{\partial y} (2 x y^{4} e^{y} + 2 x y^{3} + y)

2 x (4 y^{3} e^{y} + e^{y} y^{4}) + 6 x y^{2} + 1

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (2 x y^{4} e^{y}) + \frac{\partial}{\partial y} (2 x y^{3}) + \frac{\partial}{\partial y} (y)

\frac{\partial}{\partial y} (2 x y^{4} e^{y}) = 2 x (4 y^{3} e^{y} + e^{y} y^{4})

\frac{\partial}{\partial y} (2 x y^{3}) = 6 x y^{2}

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

= 2 x (4 y^{3} e^{y} + e^{y} y^{4}) + 6 x y^{2} + 1
