1.35272 \dots

Schritte zur Lösung

\int_{- 3}^{- 2} 2 e^{- 0.1 y} + \frac{3}{y} d y

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 3}^{- 2} 2 e^{- 0.1 y} d y + \int_{- 3}^{- 2} \frac{3}{y} d y

\int_{- 3}^{- 2} 2 e^{- 0.1 y} d y = 2.56912 \dots

\int_{- 3}^{- 2} \frac{3}{y} d y = 3 (ln (2) - ln (3))

= 2.56912 \dots + 3 (ln (2) - ln (3))

Vereinfache

2.56912 \dots + 3 (ln (2) - ln (3)) : 1.35272 \dots

= 1.35272 \dots
