Schritte zur Lösung

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

\int_{1}^{4} 3 x d x = \frac{45}{2}

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

= \frac{45}{2} + 3

Vereinfache

\frac{45}{2} + 3 : \frac{51}{2}

= \frac{51}{2}

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

\int_{5}^{7} x^{2} + 2 x + 2 - 18 d x

\int_{- 2}^{2} (10 x^{9} + 25 x^{3}) d x

\int_{1}^{2} \frac{1}{( x - 3 ) ^{2}} d x

\int_{1}^{y} \frac{1}{y ^{2}} d y
