integral of 1/(sqrt(x^2+2x-24))

Lösung

\int \frac{1}{x ^{2} + 2 x - 24} d x

ln (\frac{1}{5} x^{2} + 2 x - 24 + x + 1) + C

Schritte zur Lösung

\int \frac{1}{x ^{2} + 2 x - 24} d x

Vervollständige das Quadrat

x^{2} + 2 x - 24 : (x + 1)^{2} - 25

= \int \frac{1}{( x + 1 ) ^{2} - 25} d x

Wende U-Substitution an

= \int \frac{1}{u ^{2} - 25} d u

Trigonometrische Substitution anwenden

= \int sec (v) d v

Nutze das gemeinsame Integral :

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

= ln ∣ tan (v) + sec (v) ∣

Ersetze zurück

= ln tan (arcsec (\frac{1}{5} (x + 1))) + sec (arcsec (\frac{1}{5} (x + 1)))

Vereinfache

ln tan (arcsec (\frac{1}{5} (x + 1))) + sec (arcsec (\frac{1}{5} (x + 1))) : ln (\frac{1}{5} x^{2} + 2 x - 24 + x + 1)

= ln (\frac{1}{5} x^{2} + 2 x - 24 + x + 1)
