\frac{1 - ( - 1 ) ^{n}}{n}

\frac{1}{n} - \frac{( - 1 ) ^{n}}{n}

Schritte zur Lösung

\frac{1 - ( - 1 ) ^{n}}{n}

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{1 - ( - 1 ) ^{n}}{n} = \frac{1}{n} - \frac{( - 1 ) ^{n}}{n}

= \frac{1}{n} - \frac{( - 1 ) ^{n}}{n}

e x p an d \frac{x ^{2} + 4}{x ( x ^{2} - 4 )}

e x p an d \frac{w ^{2} + 6 w + 18}{( w + 6 ) ( w + 4 )}

e x p an d (t^{\frac{1}{2}} x^{\frac{1}{2}} + t^{\frac{1}{3}} y^{\frac{1}{3}})^{3}

e x p an d 2 x (1 + y^{2}) \cdot d x - y (1 + 2 x^{2}) \cdot d y

e x p an d (3 a + 3 b)^{3}
