integral of x/((x-3)^2)

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

ln ∣ x - 3 ∣ - \frac{3}{x - 3} + C

Solution steps

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

Apply u-substitution

: \int \frac{u + 3}{u ^{2}} d u

= \int \frac{u + 3}{u ^{2}} d u

Expand

\frac{u + 3}{u ^{2}} : \frac{1}{u} + \frac{3}{u ^{2}}

= \int \frac{1}{u} + \frac{3}{u ^{2}} d u

Apply the Sum Rule:

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

= \int \frac{1}{u} d u + \int \frac{3}{u ^{2}} d u

\int \frac{1}{u} d u = ln ∣ u ∣

\int \frac{3}{u ^{2}} d u = - \frac{3}{u}

= ln ∣ u ∣ - \frac{3}{u}

Substitute back

u = x - 3

= ln ∣ x - 3 ∣ - \frac{3}{x - 3}

Add a constant to the solution

= ln ∣ x - 3 ∣ - \frac{3}{x - 3} + C

\frac{\partial}{\partial x} (\frac{y ^{2}}{4 - x ^{2}})

\int \frac{1}{- x ^{2} + 6 x - 10} d x

\frac{d}{d x} ((sinh (x))^{2 x^{2} + 2 x})

\int \frac{( ln ( x ) ) ^{2}}{2} d x

y^{^{'}} = 6 y^{2} + x y^{2}, y (0) = 1
