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

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

0

Solution steps

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

Apply u-substitution

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

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

Apply Integration By Parts

: [\frac{1}{2} e^{u^{2}} u^{2} - \int e^{u^{2}} u^{3} d u]_{- 1}^{1}

= [\frac{1}{2} e^{u^{2}} u^{2} - \int e^{u^{2}} u^{3} d u]_{- 1}^{1}

\int e^{u^{2}} u^{3} d u = \frac{1}{2} (e^{u^{2}} u^{2} - e^{u^{2}})

= [\frac{1}{2} e^{u^{2}} u^{2} - \frac{1}{2} (e^{u^{2}} u^{2} - e^{u^{2}})]_{- 1}^{1}

Simplify

[\frac{1}{2} e^{u^{2}} u^{2} - \frac{1}{2} (e^{u^{2}} u^{2} - e^{u^{2}})]_{- 1}^{1} : [\frac{1}{2} e^{u^{2}}]_{- 1}^{1}

= [\frac{1}{2} e^{u^{2}}]_{- 1}^{1}

Compute the boundaries:

0

= 0

\int_{- 4}^{4} - x^{2} - 3 x d x

\int_{0}^{2} (3 t - 1)^{56} d t

\int_{1}^{e^{- x^{2}}} (ln (t))^{4} d t

\int_{0}^{\frac{1}{5}} \frac{1}{100 x ^{2} + 4} d x

\int_{1}^{4} e^{b x - b} d x
