integral from 0 to 2 of x(e^{x^2}-e^4)

\int_{0}^{2} x (e^{x^{2}} - e^{4}) d x

\frac{e ^{4} - 1}{2} - e^{4} \cdot 2

Decimal Notation

- 82.39722 \dots

Solution steps

\int_{0}^{2} x (e^{x^{2}} - e^{4}) d x

Expand

x (e^{x^{2}} - e^{4}) : e^{x^{2}} x - e^{4} x

= \int_{0}^{2} e^{x^{2}} x - e^{4} x d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{2} e^{x^{2}} x d x - \int_{0}^{2} e^{4} x d x

\int_{0}^{2} e^{x^{2}} x d x = \frac{e ^{4} - 1}{2}

\int_{0}^{2} e^{4} x d x = e^{4} \cdot 2

= \frac{e ^{4} - 1}{2} - e^{4} \cdot 2

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

\int_{0}^{1} \frac{16 x}{x ^{2} + 1} d x

\int_{0}^{1} x^{10} \cdot e^{- x} d x

\int_{1}^{3} (x + 5) d x

\int_{0}^{\frac{π}{2}} x^{2} cos (3 x) d x
