integral from 0 to pi of e^{-x}sin(x)

\int_{0}^{π} e^{- x} sin (x) d x

\frac{1}{2 e ^{π}} + \frac{1}{2}

Decimal Notation

0.52160 \dots

Solution steps

\int_{0}^{π} e^{- x} sin (x) d x

Compute the indefinite integral:

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

Compute the boundaries:

\int_{0}^{π} e^{- x} sin (x) d x = \frac{1}{2 e ^{π}} - (- \frac{1}{2})

= \frac{1}{2 e ^{π}} - (- \frac{1}{2})

Simplify

= \frac{1}{2 e ^{π}} + \frac{1}{2}

\int_{0}^{2} \frac{1}{( x - 1 ) ( x - 3 )} d x

\int_{0}^{\frac{π}{4}} x tan (x) d x

\int_{3}^{4} \frac{1}{( x + y ) ^{2}} d x

\int_{0}^{3} \frac{x}{x + 1} d x

\int_{0}^{1} [\frac{y}{e ^{2 y}}] d y
