integral of (8x^3+3x^2+5x+3)

Lösung

\int (8 x^{3} + 3 x^{2} + 5 x + 3) d x

2 x^{4} + x^{3} + \frac{5 x ^{2}}{2} + 3 x + C

Schritte zur Lösung

\int 8 x^{3} + 3 x^{2} + 5 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 8 x^{3} d x + \int 3 x^{2} d x + \int 5 x d x + \int 3 d x

\int 8 x^{3} d x = 2 x^{4}

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

\int 5 x d x = \frac{5 x ^{2}}{2}

\int 3 d x = 3 x

= 2 x^{4} + x^{3} + \frac{5 x ^{2}}{2} + 3 x

\int (- 4 x + 1) (sin (x)) d x

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

\int \frac{6}{9 - ( x + 3 ) ^{2}} d x

\int \frac{8 x ^{3}}{x ^{4} + 9} d x

\int \frac{1}{7 s - 6} d s
