integral from 0 to 0.5 of (sin(3x))/x

Lösung

\int_{0}^{0.5} \frac{sin ( 3 x )}{x} d x

Si (1.5)

Schritte zur Lösung

\int_{0}^{0.5} \frac{sin ( 3 x )}{x} d x

Wende U-Substitution an

= \int_{0}^{1.5} \frac{sin ( u )}{u} d u

Das ist ein nicht elementares Integral :

\int \frac{sin ( x )}{x} d x = Si (x)

= [Si (u)]_{0}^{1.5}

Berechne die Grenzen:

Si (1.5)

= Si (1.5)

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

\int_{1}^{6} x^{2} - 2 x - 8 d x

\int_{1}^{4} x^{2} + 4 x + 5 d x

\int_{0}^{1} x^{2} - 4 x + 3 d x

\int_{0}^{y} e^{y^{2}} d y
