integral of 2x^2+x-5

Lösung

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

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

Schritte zur Lösung

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

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

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

\int 5 d x = 5 x

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

Füge eine Konstante zur Lösung hinzu

= \frac{2 x ^{3}}{3} + \frac{x ^{2}}{2} - 5 x + C

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

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

\int (x + 2) \cdot sin (x^{2} + 4 x - 6) d x

\int sec^{3} (x) tan^{7} (x) d x

\int (4 - sin (\frac{t}{2}))^{2} cos (\frac{t}{2}) d t
