    Otra técnica de integración hace uso de la regla del producto para la diferenciación. Desde

    \[(fg)'=f'g+fg',\nonumber \]

    tenemos

    \[f'g=(fg)'-fg'.\nonumber \]

    Por lo tanto,

    \[\int f'(x)g(x)dx=f(x)g(x)-\int f(x)g'(x)dx.\nonumber \]

    Comúnmente, la integral anterior se realiza por escrito

    \[\begin{array}{cc}u=g(x)&dv=f'(x)dx \\ du=g'(x)dx&v=f(x).\end{array}\nonumber \]

    Entonces, la fórmula a memorizar es

    \[\int udv=uv-\int vdu.\nonumber \]
