integral of tan^2(x)(sec^2(x)-1)

Lösung

\int tan^{2} (x) (sec^{2} (x) - 1) d x

Lösung

\frac{1}{3} tan^{3} (x) + x - tan (x) + C

Schritte zur Lösung

\int tan^{2} (x) (sec^{2} (x) - 1) d x

Multipliziere aus

tan^{2} (x) (sec^{2} (x) - 1) : tan^{2} (x) sec^{2} (x) - tan^{2} (x)

= \int tan^{2} (x) sec^{2} (x) - tan^{2} (x) d x

Wende die Summenregel an:

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

= \int tan^{2} (x) sec^{2} (x) d x - \int tan^{2} (x) d x

\int tan^{2} (x) sec^{2} (x) d x = \frac{tan ^{3} ( x )}{3}

\int tan^{2} (x) d x = - x + tan (x)

= \frac{tan ^{3} ( x )}{3} - (- x + tan (x))

Vereinfache

\frac{tan ^{3} ( x )}{3} - (- x + tan (x)) : \frac{1}{3} tan^{3} (x) + x - tan (x)

= \frac{1}{3} tan^{3} (x) + x - tan (x)
