integral from-infinity to 1 of xe^x

\int_{- \infty}^{1} x e^{x} d x

0

Solution steps

\int_{- \infty}^{1} x e^{x} d x

Compute the indefinite integral:

\int x e^{x} d x = e^{x} x - e^{x} + C

Compute the boundaries:

\int_{- \infty}^{1} x e^{x} d x = 0 - 0

= 0 - 0

Simplify

= 0

\int sin (x^{2} + 1) d x

\int_{- 2}^{4} (- x^{2} + 2 x + 8) d x

\frac{d y}{d x} = (sin^{2} (2 x)) (cos^{2} (y))

t \frac{d y}{d t} = t^{3} + 20 t^{3} y

\int 1.5 sin (- x + 2) d x
