erweitern f'(x)(1-3x^2)^3

Lösung

erweitern

f^{'} (x) (1 - 3 x^{2})^{3}

f' (x) - 9 x^{2} f' (x) + 27 x^{4} f' (x) - 27 x^{6} f' (x)

Schritte zur Lösung

f^{'} (x) (1 - 3 x^{2})^{3}

(1 - 3 x^{2})^{3} = 1 - 9 x^{2} + 27 x^{4} - 27 x^{6}

= f^{^{'}} (x) (- 27 x^{6} + 27 x^{4} - 9 x^{2} + 1)

Setze Klammern

= f^{^{'}} (x) 1 + f^{^{'}} (x) (- 9 x^{2}) + f^{^{'}} (x) 27 x^{4} + f^{^{'}} (x) (- 27 x^{6})
