\frac{1}{4} (- x^{2} + 6 x - 8)

Schritte zur Lösung

\int_{2}^{x} \frac{3 - x}{2} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int_{2}^{x} 3 - x 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

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

\int_{2}^{x} 3 d x = 3 x - 6

\int_{2}^{x} x d x = \frac{x ^{2}}{2} - 2

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

Vereinfache

\frac{1}{2} (3 x - 6 - (\frac{x ^{2}}{2} - 2)) : \frac{1}{4} (- x^{2} + 6 x - 8)

= \frac{1}{4} (- x^{2} + 6 x - 8)

\int_{2}^{6} 5 d x

\int_{0}^{6} (x - 6)^{2} d x

\int_{0}^{4} (\frac{x}{1 + 2 x}) d x

\int_{0}^{21} - 117 x + 23273 d x

\int_{- π}^{5 π} cos^{2} (x) d x
