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

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

diverges

Solution steps

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

Apply u-substitution

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

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

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

Take the constant out:

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

= - (- \int_{- 1}^{0} \frac{1}{u ^{2}} d u)

Apply the Power Rule

= - (- [- \frac{1}{u}]_{- 1}^{0})

Simplify

= [- \frac{1}{u}]_{- 1}^{0}

Compute the boundaries:

diverges

= diverges
