integral from-2 to 1 of (2x+pi)

Solution

\int_{- 2}^{1} (2 x + π) d x

Solution

- 3 + 3 π

+1

Decimal Notation

6.42477 \dots

Solution steps

\int_{- 2}^{1} 2 x + π 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_{- 2}^{1} 2 x d x + \int_{- 2}^{1} π d x

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

\int_{- 2}^{1} π d x = 3 π

= - 3 + 3 π
