integral of (x 3/2)/(x+1)

\int \frac{x \frac{3}{2}}{x + 1} d x

\frac{3}{2} (x + 1 - ln ∣ x + 1 ∣) + C

Solution steps

\int \frac{x \frac{3}{2}}{x + 1} d x

Take the constant out:

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

= \frac{3}{2} \cdot \int \frac{x}{x + 1} d x

Apply u-substitution

: \int \frac{u - 1}{u} d u

= \frac{3}{2} \cdot \int \frac{u - 1}{u} d u

Expand

\frac{u - 1}{u} : 1 - \frac{1}{u}

= \frac{3}{2} \cdot \int 1 - \frac{1}{u} 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

= \frac{3}{2} (\int 1 d u - \int \frac{1}{u} d u)

\int 1 d u = u

\int \frac{1}{u} d u = ln ∣ u ∣

= \frac{3}{2} (u - ln ∣ u ∣)

Substitute back

u = x + 1

= \frac{3}{2} (x + 1 - ln ∣ x + 1 ∣)

Add a constant to the solution

= \frac{3}{2} (x + 1 - ln ∣ x + 1 ∣) + C

cos (100 t + 30)

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

N + 1 X

y^{^{''}} + 16 y = e^{2 t} tan (4 t)

x \to 2 lim ((x^{2} + 8) (2 x - 4))
