Schritte zur Lösung

\int_{0}^{t} e^{4 t} d t

Wende U-Substitution an

= \int_{0}^{4 t} e^{u} \frac{1}{4} d u

Entferne die Konstante:

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

= \frac{1}{4} \cdot \int_{0}^{4 t} e^{u} d u

Nutze das gemeinsame Integral :

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

= \frac{1}{4} [e^{u}]_{0}^{4 t}

Berechne die Grenzen:

e^{4 t} - 1

= \frac{1}{4} (e^{4 t} - 1)

\int_{1}^{2} x^{2} - 5 x + 6 d x

\int_{- 1}^{1} 3 x^{3} - 2 x + 5 d x

\int_{0}^{4} (4 - t) (t) d t

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

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