integral of (3-x^2+4x^5-2x^{-3})

Lösung

\int (3 - x^{2} + 4 x^{5} - 2 x^{- 3}) d x

3 x - \frac{x ^{3}}{3} + \frac{2 x ^{6}}{3} + \frac{1}{x ^{2}} + C

Schritte zur Lösung

\int 3 - x^{2} + 4 x^{5} - 2 x^{- 3} 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 3 d x - \int x^{2} d x + \int 4 x^{5} d x - \int 2 x^{- 3} d x

\int 3 d x = 3 x

\int x^{2} d x = \frac{x ^{3}}{3}

\int 4 x^{5} d x = \frac{2 x ^{6}}{3}

\int 2 x^{- 3} d x = - \frac{1}{x ^{2}}

= 3 x - \frac{x ^{3}}{3} + \frac{2 x ^{6}}{3} - (- \frac{1}{x ^{2}})

Vereinfache

= 3 x - \frac{x ^{3}}{3} + \frac{2 x ^{6}}{3} + \frac{1}{x ^{2}}

\int \frac{2}{e ^{x} + 1} d x

\int 1 + 4 x + x^{2} d x

\int \frac{1}{( x + 1 ) ^{3} \cdot x ^{2} + 2 x} d x

\int \frac{x ^{2} - 4 x + 4}{x ^{2} - 4 x + 8} d x

\int \frac{( x ^{2} + 3 x ) ( 5 x + 3 )}{x} d x
