\frac{1}{2} sin (x)

Schritte zur Lösung

\int_{0}^{x} x cos (x^{2}) d x

Wende U-Substitution an

= \int_{0}^{x} \frac{cos ( u )}{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_{0}^{x} cos (u) d u

Nutze das gemeinsame Integral :

\int cos (u) d u = sin (u)

= \frac{1}{2} [sin (u)]_{0}^{x}
