integral from-infinity to-2 of e^x

\int_{- \infty}^{- 2} e^{x} d x

\frac{1}{e ^{2}}

Decimal

0.13533 \dots

Solution steps

\int_{- \infty}^{- 2} e^{x} d x

Compute the indefinite integral:

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

Compute the boundaries:

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

= \frac{1}{e ^{2}} - 0

Simplify

= \frac{1}{e ^{2}}

\int_{0}^{2 π} cos (4 x) d x

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

\int_{\frac{1}{2}}^{1} \frac{8}{x ^{3}} d x

\int_{3}^{6} 8 x - 24 d x

\int_{1}^{2} (2 x^{2} + 3) d x
