integral from 0 to 1 of 1/(x^3+x^2)

\int_{0}^{1} \frac{1}{x ^{3} + x ^{2}} d x

diverges

Solution steps

\int_{0}^{1} \frac{1}{x ^{3} + x ^{2}} d x

Take the partial fraction of

\frac{1}{x ^{3} + x ^{2}} : - \frac{1}{x} + \frac{1}{x ^{2}} + \frac{1}{x + 1}

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int_{0}^{1} \frac{1}{x} d x =

diverges

If part of the expression diverges, then entire expression diverges

= diverges
