integral from 1 to 3 of (x^3+1)

Lösung

\int_{1}^{3} (x^{3} + 1) d x

22

Schritte zur Lösung

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

\int_{1}^{3} x^{3} d x = 20

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

= 20 + 2

= 22

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

\int_{4}^{7} (2 x + 1) e^{0.4 x} d x

\int_{0}^{l o g_{3} (5)} 3^{x} d x

\int_{0}^{2} \frac{6 x ^{2}}{2 + x ^{3}} d x

\int_{1}^{5} ln (2 x) - ln (x) d x
