Schritte zur Lösung

\frac{\partial}{\partial x} ((3 x - 1)^{2} (x^{3} + 1)^{2})

Wende die Produktregel an:

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

f = (3 x - 1)^{2}, g = (x^{3} + 1)^{2}

= \frac{\partial}{\partial x} ((3 x - 1)^{2}) (x^{3} + 1)^{2} + \frac{\partial}{\partial x} ((x^{3} + 1)^{2}) (3 x - 1)^{2}

\frac{\partial}{\partial x} ((3 x - 1)^{2}) = 6 (3 x - 1)

\frac{\partial}{\partial x} ((x^{3} + 1)^{2}) = 6 x^{2} (x^{3} + 1)

= 6 (3 x - 1) (x^{3} + 1)^{2} + 6 x^{2} (x^{3} + 1) (3 x - 1)^{2}

Vereinfache

6 (3 x - 1) (x^{3} + 1)^{2} + 6 x^{2} (x^{3} + 1) (3 x - 1)^{2} : 72 x^{7} - 42 x^{6} + 6 x^{5} + 90 x^{4} - 48 x^{3} + 6 x^{2} + 18 x - 6

= 72 x^{7} - 42 x^{6} + 6 x^{5} + 90 x^{4} - 48 x^{3} + 6 x^{2} + 18 x - 6

d er i v a t i v e y = (x + 3)^{3}

\frac{d y}{d t} = - \frac{y}{t}

\int \frac{6}{x ^{2} - 1} d x

d er i v a t i v e f (x) = 4 x^{2} sin (x) - 7 x

\int_{0}^{5} \frac{1}{3 x + 1} d x
