Schritte zur Lösung

\int_{0}^{1} x^{3} + 3 x + 4 d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{1} x^{3} d x + \int_{0}^{1} 3 x d x + \int_{0}^{1} 4 d x

\int_{0}^{1} x^{3} d x = \frac{1}{4}

\int_{0}^{1} 3 x d x = \frac{3}{2}

\int_{0}^{1} 4 d x = 4

= \frac{1}{4} + \frac{3}{2} + 4

Vereinfache

\frac{1}{4} + \frac{3}{2} + 4 : \frac{23}{4}

= \frac{23}{4}

\int_{- 2}^{2} 4 - y^{2} d y

\int_{- 1}^{2} \frac{x}{x ^{2} + 1} d x

\int_{0}^{\frac{1}{2}} \frac{1}{x ln ^{2} ( x )} d x

\int_{0}^{\infty} \frac{1}{2 + x ^{2}} d x

\int_{1}^{6} 2^{x} d x
