Schritte zur Lösung

\int_{- 2}^{6} 4 x - x^{2} + 12 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}^{6} 4 x d x - \int_{- 2}^{6} x^{2} d x + \int_{- 2}^{6} 12 d x

\int_{- 2}^{6} 4 x d x = 64

\int_{- 2}^{6} x^{2} d x = \frac{224}{3}

\int_{- 2}^{6} 12 d x = 96

= 64 - \frac{224}{3} + 96

Vereinfache

64 - \frac{224}{3} + 96 : \frac{256}{3}

= \frac{256}{3}

y^{^{''}} + 5 y^{^{'}} = e^{- t}, y (0) = 0, y^{^{'}} (0) = 1

x \to 4 lim (f (x))

f (x) = - \frac{1}{x}

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

\int \frac{x ^{4}}{x ^{2} - 9} d x
