vereinfachen ln(1+x^2)+1/2 ln(x)-ln(sin(x))

Lösung

vereinfachen

ln (1 + x^{2}) + \frac{1}{2} ln (x) - ln (sin (x))

ln (x^{\frac{1}{2}} csc (x) (1 + x^{2}))

Schritte zur Lösung

ln (1 + x^{2}) + \frac{1}{2} ln (x) - ln (sin (x))

Wende die log Regel an:

a lo g_{c} (b) = lo g_{c} (b^{a})

\frac{1}{2} ln (x) = ln (x^{\frac{1}{2}})

= ln (x^{2} + 1) + ln (x^{\frac{1}{2}}) - ln (sin (x))

Wende die log Regel an:

lo g_{c} (a) + lo g_{c} (b) = lo g_{c} (ab)

ln (1 + x^{2}) + ln (x^{\frac{1}{2}}) = ln (x^{\frac{1}{2}} (x^{2} + 1))

= ln ((1 + x^{2}) x^{\frac{1}{2}}) - ln (sin (x))

Wende die log Regel an:

lo g_{c} (a) - lo g_{c} (b) = lo g_{c} (\frac{a}{b})

ln (x^{\frac{1}{2}} (1 + x^{2})) - ln (sin (x)) = ln (\frac{x ^{\frac{1}{2}} ( x ^{2} + 1 )}{sin ( x )})

= ln (\frac{( 1 + x ^{2} ) x ^{\frac{1}{2}}}{sin ( x )})

Verwende die grundlegende trigonometrische Identität:

\frac{1}{sin ( x )} = csc (x)

= ln (x^{\frac{1}{2}} csc (x) (1 + x^{2}))
