integral from 2 to infinity of-5x^{-2}

\int_{2}^{\infty} - 5 x^{- 2} d x

- \frac{5}{2}

Decimal Notation

- 2.5

Solution steps

\int_{2}^{\infty} - 5 x^{- 2} d x

Compute the indefinite integral:

\int - 5 x^{- 2} d x = \frac{5}{x} + C

Compute the boundaries:

\int_{2}^{\infty} - 5 x^{- 2} d x = 0 - \frac{5}{2}

= 0 - \frac{5}{2}

Simplify

= - \frac{5}{2}

\frac{d}{d x} (5 x e^{4 x})

\frac{\partial}{\partial x} (\frac{63}{( 9 + x ^{2} + y ^{2} )})

\frac{\partial}{\partial z} (\frac{1}{x ^{2} yz})

\int 9 + 4 x^{2} d x

\frac{( s + 2 )}{s ^{2} + s + 1} - \frac{1}{s}
