integral from 1 to 2 of xe^{2x^2-3}

\int_{1}^{2} x e^{2 x^{2} - 3} d x

\frac{e ^{6} - 1}{4 e}

Decimal Notation

37.01131 \dots

Solution steps

\int_{1}^{2} x e^{2 x^{2} - 3} d x

Apply u-substitution

: \int_{- 1}^{5} \frac{e ^{u}}{4} d u

= \int_{- 1}^{5} \frac{e ^{u}}{4} d u

Take the constant out:

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

= \frac{1}{4} \cdot \int_{- 1}^{5} e^{u} d u

Use the common integral:

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

= \frac{1}{4} [e^{u}]_{- 1}^{5}

Compute the boundaries:

e^{5} - \frac{1}{e}

= \frac{1}{4} (e^{5} - \frac{1}{e})

Simplify

= \frac{e ^{6} - 1}{4 e}

\int_{0}^{π} 10 t sin (3 t) d t

f (x) = x^{4} + 9 x^{2} - x, (1, 9)

x \to \infty lim (\frac{x \cdot ( x + 1 ) ^{x + 1}}{( x + 1 ) ^{x + 2}})

\frac{1}{( 8 ^{2} + 1 ) + ( 8 ^{2} + 4 )}

\int 2 e^{- 0.4 x} d x
