integral of (sqrt(x)+2ln(x))/x

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

2 x + ln^{2} (x) + C

Solution steps

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

Expand

\frac{x + 2 ln ( x )}{x} : \frac{1}{x} + \frac{2 ln ( x )}{x}

= \int \frac{1}{x} + \frac{2 ln ( x )}{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 \frac{1}{x} d x + \int \frac{2 ln ( x )}{x} d x

\int \frac{1}{x} d x = 2 x

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

= 2 x + ln^{2} (x)

Add a constant to the solution

= 2 x + ln^{2} (x) + C

\int x^{\frac{1}{3}} cos (x^{\frac{4}{3}} - 8) d x

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

\int x^{3} (7 + x^{4})^{4} d x

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

\int (x^{2} - 6 x) 3^{4 x} d x
