integral from-3 to 2 of 2xe^x

\int_{- 3}^{2} 2 x e^{x} d x

2 (e^{2} + \frac{4}{e ^{3}})

Solution steps

\int_{- 3}^{2} 2 x e^{x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{- 3}^{2} x e^{x} d x

Apply Integration By Parts

: [e^{x} x - \int e^{x} d x]_{- 3}^{2}

= 2 [e^{x} x - \int e^{x} d x]_{- 3}^{2}

\int e^{x} d x = e^{x}

= 2 [e^{x} x - e^{x}]_{- 3}^{2}

Compute the boundaries:

e^{2} + \frac{4}{e ^{3}}

= 2 (e^{2} + \frac{4}{e ^{3}})

\int_{- \infty}^{l n (7)} e^{x} d x

\int_{0}^{3} x 1 + 4 x^{2} d x

\int_{0}^{2} 3 x^{2} - 2 x + 1 d x

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