integral of x^2-5x+5

Lösung

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

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

Schritte zur Lösung

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

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

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

\int 5 d x = 5 x

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

Füge eine Konstante zur Lösung hinzu

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

\int_{\frac{π}{2}}^{π} 4 cot (\frac{x}{2}) d x

\frac{\partial}{\partial x} (y^{2} e^{2 x})

\frac{d}{d x} (e^{x^{2} - 4} + 2 x + 9)

\frac{d}{d x} (tan^{4} (cot (3 x^{4} + 5 x)))

x \frac{d y}{d x} = x^{3} + 24 x^{3} y
