\frac{- e ^{4} - 3}{4}

خطوات الحلّ

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

فعّل التكامل بالتجزيء

: [\frac{1}{2} e^{2 x} (1 - x) - \int - \frac{1}{2} e^{2 x} d x]_{0}^{2}

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

\int - \frac{1}{2} e^{2 x} d x = - \frac{1}{4} e^{2 x}

= [\frac{1}{2} e^{2 x} (1 - x) - (- \frac{1}{4} e^{2 x})]_{0}^{2}

[\frac{1}{2} e^{2 x} (1 - x) - (- \frac{1}{4} e^{2 x})]_{0}^{2}

بسّط:

[\frac{1}{4} (- 2 e^{2 x} x + 3 e^{2 x})]_{0}^{2}

= [\frac{1}{4} (- 2 e^{2 x} x + 3 e^{2 x})]_{0}^{2}

احسب التكامل المحدّد:

- \frac{e ^{4}}{4} - \frac{3}{4}

= - \frac{e ^{4}}{4} - \frac{3}{4}

بسّط

= \frac{- e ^{4} - 3}{4}

\int_{0}^{1} ln (y + 1) d y
