Schritte zur Lösung

\int_{3}^{4} x x - 3 d x

Wende U-Substitution an

= \int_{0}^{1} (u + 3) u d u

Multipliziere aus

(u + 3) u : u^{\frac{3}{2}} + 3 u

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

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} u^{\frac{3}{2}} d u + \int_{0}^{1} 3 u d u

\int_{0}^{1} u^{\frac{3}{2}} d u = \frac{2}{5}

\int_{0}^{1} 3 u d u = 2

= \frac{2}{5} + 2

Vereinfache

\frac{2}{5} + 2 : \frac{12}{5}

= \frac{12}{5}

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

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

\int_{1}^{3} \frac{3 x - y}{9} d x

\int_{0}^{\frac{π}{2}} 4 d x

\int_{1}^{5} \frac{ln ( x ^{2} )}{x ^{3}} d x
