integral of (4x^3+3x+3)/x

\int \frac{4 x ^{3} + 3 x + 3}{x} d x

\frac{4 x ^{3}}{3} + 3 x + 3 ln ∣ x ∣ + C

Solution steps

\int \frac{4 x ^{3} + 3 x + 3}{x} d x

Expand

\frac{4 x ^{3} + 3 x + 3}{x} : 4 x^{2} + 3 + \frac{3}{x}

= \int 4 x^{2} + 3 + \frac{3}{x} d x

Apply the Sum Rule:

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

= \int 4 x^{2} d x + \int 3 d x + \int \frac{3}{x} d x

\int 4 x^{2} d x = \frac{4 x ^{3}}{3}

\int 3 d x = 3 x

\int \frac{3}{x} d x = 3 ln ∣ x ∣

= \frac{4 x ^{3}}{3} + 3 x + 3 ln ∣ x ∣

Add a constant to the solution

= \frac{4 x ^{3}}{3} + 3 x + 3 ln ∣ x ∣ + C

x \to 7 lim (sin (\frac{π}{x}))

\frac{\partial}{\partial y} (\frac{y}{x - 1})

y = e^{x^{3}}, (1, e)

\frac{e ^{x}}{6 + e ^{x}}

\frac{d}{d x} (\frac{1}{3 x - 4})
