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

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

e - 2

Decimal Notation

0.71828 \dots

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

: \int_{0}^{1} \frac{e ^{u} - 1}{2} d u

= 2 \cdot \int_{0}^{1} \frac{e ^{u} - 1}{2} d u

Take the constant out:

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

= 2 \cdot \frac{1}{2} \cdot \int_{0}^{1} e^{u} - 1 d u

Apply the Sum Rule:

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

= 2 \cdot \frac{1}{2} (\int_{0}^{1} e^{u} d u - \int_{0}^{1} 1 d u)

\int_{0}^{1} e^{u} d u = e - 1

\int_{0}^{1} 1 d u = 1

= 2 \cdot \frac{1}{2} (e - 1 - 1)

Simplify

2 \cdot \frac{1}{2} (e - 1 - 1) : e - 2

= e - 2

\int_{- 1}^{3} \frac{1}{x ^{4}} d x

\int_{0}^{5} 1 + 9 x d x

\int_{0}^{\frac{π}{2}} 1 + cos (2 y) d y

\int_{0}^{\infty} r^{4} e^{- r} d r
