\frac{1}{2} ln (\frac{t ^{4} - 4 + t ^{2}}{2}) + C

Schritte zur Lösung

\int \frac{t}{t ^{4} - 4} d t

Wende U-Substitution an

= \int \frac{1}{2 u ^{2} - 4} d u

Entferne die Konstante:

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

= \frac{1}{2} \cdot \int \frac{1}{u ^{2} - 4} d u

Trigonometrische Substitution anwenden

= \frac{1}{2} \cdot \int sec (v) d v

Nutze das gemeinsame Integral :

\int sec (v) d v = ln ∣ tan (v) + sec (v) ∣

= \frac{1}{2} ln ∣ tan (v) + sec (v) ∣

= \frac{1}{2} ln tan (arcsec (\frac{1}{2} t^{2})) + sec (arcsec (\frac{1}{2} t^{2}))

Vereinfache

\frac{1}{2} ln tan (arcsec (\frac{1}{2} t^{2})) + sec (arcsec (\frac{1}{2} t^{2})) : \frac{1}{2} ln (\frac{t ^{4} - 4 + t ^{2}}{2})

= \frac{1}{2} ln (\frac{t ^{4} - 4 + t ^{2}}{2})
