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

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

\frac{ln ^{2} ( 2 x )}{2} + ln ∣ x ∣ + C

Solution steps

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

Expand

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

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

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

\int \frac{1}{x} d x = ln ∣ x ∣

= \frac{ln ^{2} ( 2 x )}{2} + ln ∣ x ∣

Add a constant to the solution

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

\int \frac{1}{9 ( x ^{2} + 1 )} d x

\int x (7 x^{2} - 5)^{\frac{9}{2}} d x

\int \frac{1}{sec ( 5 x + 1 )} d x

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

\int \frac{4 ^{x}}{2 ^{x} - 1} d x
