integral from 0 to x of sqrt(t^4+t^6)

Lösung

\int_{0}^{x} t^{4} + t^{6} d t

Lösung

- \frac{x x ^{2} + 1 + ln x + x ^{2} + 1}{2} + \frac{x ( x ^{2} + 1 ) ^{\frac{3}{2}}}{4} + \frac{3 ( x x ^{2} + 1 + ln x + x ^{2} + 1 )}{8}

Schritte zur Lösung

\int_{0}^{x} t^{4} + t^{6} d t

Vereinfache

t^{4} + t^{6} : t^{2} 1 + t^{2}

= \int_{0}^{x} t^{2} 1 + t^{2} d t

Trigonometrische Substitution anwenden

= \int_{0}^{a r c t a n (x)} sec^{3} (u) tan^{2} (u) d u

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= \int_{0}^{a r c t a n (x)} sec^{3} (u) (- 1 + sec^{2} (u)) d u

Multipliziere aus

sec^{3} (u) (- 1 + sec^{2} (u)) : - sec^{3} (u) + sec^{5} (u)

= \int_{0}^{a r c t a n (x)} - sec^{3} (u) + sec^{5} (u) d u

Wende die Summenregel an:

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

= - \int_{0}^{a r c t a n (x)} sec^{3} (u) d u + \int_{0}^{a r c t a n (x)} sec^{5} (u) d u

\int_{0}^{a r c t a n (x)} sec^{3} (u) d u = \frac{x x ^{2} + 1 + ln x + x ^{2} + 1}{2}

\int_{0}^{a r c t a n (x)} sec^{5} (u) d u = \frac{x ( x ^{2} + 1 ) ^{\frac{3}{2}}}{4} + \frac{3 ( x x ^{2} + 1 + ln x + x ^{2} + 1 )}{8}

= - \frac{x x ^{2} + 1 + ln x + x ^{2} + 1}{2} + \frac{x ( x ^{2} + 1 ) ^{\frac{3}{2}}}{4} + \frac{3 ( x x ^{2} + 1 + ln x + x ^{2} + 1 )}{8}
