integral from 0 to 1 of (x^3)/(x^4-1)

\int_{0}^{1} \frac{x ^{3}}{x ^{4} - 1} d x

diverges

Solution steps

\int_{0}^{1} \frac{x ^{3}}{x ^{4} - 1} d x

Apply u-substitution

= \int_{- 1}^{0} \frac{1}{4 u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{4} \cdot \int_{- 1}^{0} \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{4} [ln ∣ u ∣]_{- 1}^{0}

Compute the boundaries:

diverges

= diverges
