\int_{0}^{2 π} sin (\frac{1}{2}) t d t

Entferne die Konstante:

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

= sin (\frac{1}{2}) \cdot \int_{0}^{2 π} t d t

Wende die Potenzregel an

= sin (\frac{1}{2}) [\frac{t ^{2}}{2}]_{0}^{2 π}

Berechne die Grenzen:

2 π^{2}

= sin (\frac{1}{2}) \cdot 2 π^{2}

\int_{1}^{2} (3 x^{2} - 4 x + 1) d x

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

\int_{- π}^{0} 2 sin (n x) d x

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

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