derivative f(x)=(3-x)^4(x+5)^3

Lösung

ableitung von

f (x) = (3 - x)^{4} (x + 5)^{3}

- 4 (3 - x)^{3} (x + 5)^{3} + 3 (x + 5)^{2} (3 - x)^{4}

Schritte zur Lösung

\frac{d}{d x} ((3 - x)^{4} (x + 5)^{3})

Wende die Produktregel an:

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

f = (3 - x)^{4}, g = (x + 5)^{3}

= \frac{d}{d x} ((3 - x)^{4}) (x + 5)^{3} + \frac{d}{d x} ((x + 5)^{3}) (3 - x)^{4}

\frac{d}{d x} ((3 - x)^{4}) = - 4 (3 - x)^{3}

\frac{d}{d x} ((x + 5)^{3}) = 3 (x + 5)^{2}

= (- 4 (3 - x)^{3}) (x + 5)^{3} + 3 (x + 5)^{2} (3 - x)^{4}

Vereinfache

= - 4 (3 - x)^{3} (x + 5)^{3} + 3 (x + 5)^{2} (3 - x)^{4}

\frac{d y}{d t} = y \cdot ln (y)

\frac{\partial}{\partial x} (7 x e^{x^{2} + y^{2}})

\frac{\partial}{\partial z} (\frac{x ^{2} + z ^{2}}{y} + x yz + 5 x z^{2})

\int \frac{e ^{x} + 1}{e ^{x} - 1} d x

\frac{d}{d x} (\frac{1}{3 x})
