ableitung von

f (x) = 4 e^{5 x^{2}} (5 - x)^{7}

4 (10 e^{5 x^{2}} x (5 - x)^{7} - 7 e^{5 x^{2}} (5 - x)^{6})

Schritte zur Lösung

\frac{d}{d x} (4 e^{5 x^{2}} (5 - x)^{7})

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 \frac{d}{d x} (e^{5 x^{2}} (5 - x)^{7})

Wende die Produktregel an:

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

f = e^{5 x^{2}}, g = (5 - x)^{7}

= 4 (\frac{d}{d x} (e^{5 x^{2}}) (5 - x)^{7} + \frac{d}{d x} ((5 - x)^{7}) e^{5 x^{2}})

\frac{d}{d x} (e^{5 x^{2}}) = e^{5 x^{2}} \cdot 10 x

\frac{d}{d x} ((5 - x)^{7}) = - 7 (5 - x)^{6}

= 4 (e^{5 x^{2}} \cdot 10 x (5 - x)^{7} + (- 7 (5 - x)^{6}) e^{5 x^{2}})

Vereinfache

= 4 (10 e^{5 x^{2}} x (5 - x)^{7} - 7 e^{5 x^{2}} (5 - x)^{6})

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

\int (sin (x^{2})) d x

\frac{\partial}{\partial x} (9 + x^{2} + y^{2})

\frac{d ^{2}}{d x ^{2}} (\frac{10}{3 x ^{3}})

\frac{\partial}{\partial x} (x^{2} - x y^{2} + 4 y^{5})
