integral from 0 to pi of e^{2x}cos(x)

\int_{0}^{π} e^{2 x} cos (x) d x

\frac{- 2 e ^{2 π} - 2}{5}

Decimal

- 214.59666 \dots

Solution steps

\int_{0}^{π} e^{2 x} cos (x) d x

Compute the indefinite integral:

\int e^{2 x} cos (x) d x = \frac{e ^{2 x} sin ( x )}{5} + \frac{2 e ^{2 x} cos ( x )}{5} + C

Compute the boundaries:

\int_{0}^{π} e^{2 x} cos (x) d x = - \frac{2 e ^{2 π}}{5} - \frac{2}{5}

= - \frac{2 e ^{2 π}}{5} - \frac{2}{5}

Simplify

= \frac{- 2 e ^{2 π} - 2}{5}
