integral from 0 to pi of 6e^x+7sin(x)

\int_{0}^{π} 6 e^{x} + 7 sin (x) d x

6 e^{π} + 8

Decimal

146.84415 \dots

Solution steps

\int_{0}^{π} 6 e^{x} + 7 sin (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} 6 e^{x} d x + \int_{0}^{π} 7 sin (x) d x

\int_{0}^{π} 6 e^{x} d x = 6 (e^{π} - 1)

\int_{0}^{π} 7 sin (x) d x = 14

= 6 (e^{π} - 1) + 14

Simplify

6 (e^{π} - 1) + 14 : 6 e^{π} + 8

= 6 e^{π} + 8
