integral of 5(cos(x)+sin(2x))/(sin(x))

Lösung

\int 5 \frac{cos ( x ) + sin ( 2 x )}{sin ( x )} d x

Lösung

5 (ln ∣ sin (x) ∣ + 2 sin (x)) + C

Schritte zur Lösung

\int 5 \cdot \frac{cos ( x ) + sin ( 2 x )}{sin ( x )} d x

Entferne die Konstante:

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

= 5 \cdot \int \frac{cos ( x ) + sin ( 2 x )}{sin ( x )} d x

\frac{cos ( x ) + sin ( 2 x )}{sin ( x )} : \frac{cos ( x )}{sin ( x )} + \frac{sin ( 2 x )}{sin ( x )}

= 5 \cdot \int \frac{cos ( x )}{sin ( x )} + \frac{sin ( 2 x )}{sin ( x )} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 5 (\int \frac{cos ( x )}{sin ( x )} d x + \int \frac{sin ( 2 x )}{sin ( x )} d x)

\int \frac{cos ( x )}{sin ( x )} d x = ln ∣ sin (x) ∣

\int \frac{sin ( 2 x )}{sin ( x )} d x = 2 sin (x)

= 5 (ln ∣ sin (x) ∣ + 2 sin (x))

Füge eine Konstante zur Lösung hinzu

= 5 (ln ∣ sin (x) ∣ + 2 sin (x)) + C
