integral from 1 to 2 of 1+xe^x

Solution

\int_{1}^{2} 1 + x e^{x} d x

Solution

1 + e^{2}

+1

Decimal Notation

8.38905 \dots

Solution steps

\int_{1}^{2} 1 + x e^{x} d x

Apply the Sum Rule:

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

= \int_{1}^{2} 1 d x + \int_{1}^{2} x e^{x} d x

\int_{1}^{2} 1 d x = 1

\int_{1}^{2} x e^{x} d x = e^{2}

= 1 + e^{2}
