erweitern (2+2/x)sin(x+ln(x))

Lösung

erweitern

(2 + \frac{2}{x}) sin (x + ln (x))

2 sin (x + ln (x)) + \frac{2 sin ( x + ln ( x ) )}{x}

Schritte zur Lösung

(2 + \frac{2}{x}) sin (x + ln (x))

= sin (x + ln (x)) (2 + \frac{2}{x})

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = sin (x + ln (x)), b = 2, c = \frac{2}{x}

= sin (x + ln (x)) \cdot 2 + sin (x + ln (x)) \frac{2}{x}

= 2 sin (x + ln (x)) + \frac{2}{x} sin (x + ln (x))

Multipliziere

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

= 2 sin (x + ln (x)) + \frac{2 sin ( x + ln ( x ) )}{x}
