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

\int_{0}^{3} \frac{1}{( 3 - x ) ^{2}} d x

diverges

Solution steps

\int_{0}^{3} \frac{1}{( 3 - x ) ^{2}} d x

Apply u-substitution

: \int_{3}^{0} - \frac{1}{u ^{2}} d u

= \int_{3}^{0} - \frac{1}{u ^{2}} d u

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

= - \int_{0}^{3} - \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_{0}^{3} \frac{1}{u ^{2}} d u)

Apply the Power Rule

: [- \frac{1}{u}]_{0}^{3}

= - (- [- \frac{1}{u}]_{0}^{3})

Simplify

= [- \frac{1}{u}]_{0}^{3}

Compute the boundaries:

\int_{- 1}^{3} (- x^{3} + 3 x^{2} - 5) d x

\int_{0}^{2} c (4 x - 2 x^{2}) d x

\int_{\frac{x}{4}}^{\frac{x}{2}} sin (x) d x

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

\int_{8}^{8} x 3^{x} d x
