integral of x(e^{x^2}+12)

Lösung

\int x (e^{x^{2}} + 12) d x

Lösung

\frac{1}{2} (e^{x^{2}} + 12 x^{2}) + C

Schritte zur Lösung

\int x (e^{x^{2}} + 12) d x

Wende U-Substitution an

= \int \frac{e ^{u} + 12}{2} d u

Entferne die Konstante:

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

= \frac{1}{2} \cdot \int e^{u} + 12 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

= \frac{1}{2} (\int e^{u} d u + \int 12 d u)

\int e^{u} d u = e^{u}

\int 12 d u = 12 u

= \frac{1}{2} (e^{u} + 12 u)

Setze in

u = x^{2}

ein

= \frac{1}{2} (e^{x^{2}} + 12 x^{2})

Füge eine Konstante zur Lösung hinzu

= \frac{1}{2} (e^{x^{2}} + 12 x^{2}) + C
