integral of (x+2+3/x)

\int (x + 2 + \frac{3}{x}) d x

\frac{x ^{2}}{2} + 2 x + 3 ln ∣ x ∣ + C

Solution steps

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

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

\int 2 d x = 2 x

\int \frac{3}{x} d x = 3 ln ∣ x ∣

= \frac{x ^{2}}{2} + 2 x + 3 ln ∣ x ∣

Add a constant to the solution

= \frac{x ^{2}}{2} + 2 x + 3 ln ∣ x ∣ + C

\int_{4}^{\infty} e^{- 6 x} d x

7 x^{2} - 12 x + 6

\int cos (\frac{x}{8}) d x

\int_{0}^{π} sec^{2} (\frac{x}{3}) d x

\frac{d y}{d x} = \frac{2 x ( y - 2 )}{x ^{2} + 1}
