integral from 2 to infinity of-3x^{-2}

\int_{2}^{\infty} - 3 x^{- 2} d x

- \frac{3}{2}

Decimal

- 1.5

Solution steps

\int_{2}^{\infty} - 3 x^{- 2} d x

Compute the indefinite integral:

\int - 3 x^{- 2} d x = \frac{3}{x} + C

Compute the boundaries:

\int_{2}^{\infty} - 3 x^{- 2} d x = 0 - \frac{3}{2}

= 0 - \frac{3}{2}

Simplify

= - \frac{3}{2}

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

\int (1 + x)^{- 4} d x

\frac{7 d u}{d t} = u^{2}

4 y^{^{''}} + 8 y = 0

x \to - 1 lim (sin (π x))
