integral from 0 to pi of 2+cos(x)

\int_{0}^{π} 2 + cos (x) d x

2 π

Decimal

6.28318 \dots

Solution steps

\int_{0}^{π} 2 + cos (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_{0}^{π} 2 d x + \int_{0}^{π} cos (x) d x

\int_{0}^{π} 2 d x = 2 π

\int_{0}^{π} cos (x) d x = 0

= 2 π + 0

Simplify

= 2 π
