integral from 0 to 1 of (2x+3)e^{-5x}

\int_{0}^{1} (2 x + 3) e^{- 5 x} d x

- \frac{27}{25 e ^{5}} + \frac{17}{25}

Decimal

0.67272 \dots

Solution steps

\int_{0}^{1} (2 x + 3) e^{- 5 x} d x

Apply Integration By Parts

= [- \frac{1}{5} e^{- 5 x} (2 x + 3) - \int - \frac{2}{5} e^{- 5 x} d x]_{0}^{1}

\int - \frac{2}{5} e^{- 5 x} d x = \frac{2}{25} e^{- 5 x}

= [- \frac{1}{5} e^{- 5 x} (2 x + 3) - \frac{2}{25} e^{- 5 x}]_{0}^{1}

Simplify

[- \frac{1}{5} e^{- 5 x} (2 x + 3) - \frac{2}{25} e^{- 5 x}]_{0}^{1} : [\frac{1}{25} (- 10 e^{- 5 x} x - 17 e^{- 5 x})]_{0}^{1}

= [\frac{1}{25} (- 10 e^{- 5 x} x - 17 e^{- 5 x})]_{0}^{1}

Compute the boundaries:

- \frac{27}{25 e ^{5}} + \frac{17}{25}

= - \frac{27}{25 e ^{5}} + \frac{17}{25}
