integral of 2ln(2x)

\int 2 ln (2 x) d x

2 (x ln (2 x) - x) + C

Solution steps

\int 2 ln (2 x) d x

Take the constant out:

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

= 2 \cdot \int ln (2 x) d x

Apply Integration By Parts

: x ln (2 x) - \int 1 d x

= 2 (x ln (2 x) - \int 1 d x)

\int 1 d x = x

= 2 (x ln (2 x) - x)

Add a constant to the solution

= 2 (x ln (2 x) - x) + C

\int cos^{3} (x) sin^{11} (x) d x

\int (x^{2})^{\frac{1}{3}} d x

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

\int \frac{e ^{2 x}}{8 + e ^{4 x}} d x

\int \frac{ln ( 8 x )}{x ^{7}} d x
