integral from 1 to 2 of (x/(x^2-3))

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

diverges

Solution steps

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

Find undefined (singularity) points:

x = 3

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}^{3} \frac{x}{x ^{2} - 3} d x + \int_{3}^{2} \frac{x}{x ^{2} - 3} d x

\int_{1}^{3} \frac{x}{x ^{2} - 3} d x =

diverges

If part of the expression diverges, then entire expression diverges

= diverges
