integral of ((x^2-1)^2)/(x^2)

Lösung

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

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

Schritte zur Lösung

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

Wende die partielle Integration an

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

\int \frac{2 ( x ^{2} - 1 ) ( x ^{2} + 1 )}{x ^{2}} d x = 2 (- \frac{( x ^{2} - 1 ) ( x ^{2} + 1 )}{x} + \frac{4 x ^{3}}{3})

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