Lösung

\int_{1}^{3} 12 x^{2} d x

104

Schritte zur Lösung

\int_{1}^{3} 12 x^{2} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 12 \cdot \int_{1}^{3} x^{2} d x

Wende die Potenzregel an

= 12 [\frac{x ^{3}}{3}]_{1}^{3}

Berechne die Grenzen:

\frac{26}{3}

= 12 \cdot \frac{26}{3}

Vereinfache

= 104

\int_{0}^{1} 2 - t^{2} d t

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

\int_{0}^{1} \frac{e ^{x} + 3}{e ^{x}} d x

\int_{0}^{3} 5 t - 8 d t

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