integral from 1/2 to 5 of 12xln(2x)

\int_{\frac{1}{2}}^{5} 12 x ln (2 x) d x

12 (- \frac{99}{16} + \frac{25}{2} ln (10))

Decimal Notation

271.13776 \dots

Solution steps

\int_{\frac{1}{2}}^{5} 12 x ln (2 x) d x

Take the constant out:

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

= 12 \cdot \int_{\frac{1}{2}}^{5} x ln (2 x) d x

Apply Integration By Parts

: [\frac{1}{2} x^{2} ln (2 x) - \int \frac{x}{2} d x]_{\frac{1}{2}}^{5}

= 12 [\frac{1}{2} x^{2} ln (2 x) - \int \frac{x}{2} d x]_{\frac{1}{2}}^{5}

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

= 12 [\frac{1}{2} x^{2} ln (2 x) - \frac{x ^{2}}{4}]_{\frac{1}{2}}^{5}

Compute the boundaries:

- \frac{99}{16} + \frac{25}{2} ln (10)

= 12 (- \frac{99}{16} + \frac{25}{2} ln (10))

\frac{3}{x}
