\int_{1}^{9} \frac{1}{x} d x

Nutze das gemeinsame Integral :

\int \frac{1}{x} d x = ln (∣ x ∣)

= [ln ∣ x ∣]_{1}^{9}

Berechne die Grenzen:

2 ln (3)

= 2 ln (3)

\int (x^{2} - 4) d x

t an g e n t f (x) = x^{3} - 2 x + 2, (3, 23)

\int_{0}^{x^{3}} (t + 1) (t - 2) d t

\frac{d}{d x} (\frac{x ^{4} + 2 x - 1}{5 x ^{2} - 2 x + 1})

\int \frac{x ^{2}}{x ^{2} + 4} d x
