integral from-1 to 2 of x^{-2}

\int_{- 1}^{2} x^{- 2} d x

diverges

Solution steps

\int_{- 1}^{2} x^{- 2} d x

Find undefined (singularity) points:

x = 0

If exist

b, a < b < c, f (b) =

undefined

, \int_{a}^{c} f (x) d x = \int_{a}^{b} f (x) d x + \int_{b}^{c} f (x) d x

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

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

diverges

If part of the expression diverges, then entire expression diverges

= diverges
