Schritte zur Lösung

\int_{2}^{5} ln (x) + sin (x) + 8 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_{2}^{5} ln (x) d x + \int_{2}^{5} sin (x) d x + \int_{2}^{5} 8 d x

\int_{2}^{5} ln (x) d x = 5 ln (5) - 3 - 2 ln (2)

\int_{2}^{5} sin (x) d x = - cos (5) + cos (2)

\int_{2}^{5} 8 d x = 24

= 5 ln (5) - 3 - 2 ln (2) - cos (5) + cos (2) + 24

Vereinfache

= 5 ln (5) + 21 + cos (2) - 2 ln (2) - cos (5)

\int_{\frac{y}{n}}^{1} n (1 - x)^{n - 1} d x

\int_{8}^{125} 3 x d x

\int_{1}^{3} (x^{2} - 8 x + 15) d x

\int_{0}^{x} \frac{e ^{2 s} - 1}{s} d s

\int_{1}^{4} 4^{5 x} d x
