integral from 2 to infinity of-2x^{-2}

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

- 1

Solution steps

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

Compute the indefinite integral:

\int - 2 x^{- 2} d x = \frac{2}{x} + C

Compute the boundaries:

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

= 0 - 1

Simplify

= - 1

\frac{d}{d x} (\frac{2}{4 x - 3})

\int \frac{t ^{3}}{a ^{4} + t ^{4}} d t

\frac{d}{d x} (arctan (7 x))

y^{^{'}} = x - y + 1

f (x) = \frac{1300 + 8 x - 0.0004 x ^{2}}{x}
