    Se pueden integrar funciones más complicadas usando la regla de cadena. Ya\[\frac{d}{dx}f(g(x))=f'(g(x))\cdot g'(x),\nonumber\] que tenemos\[\int f'(g(x))\cdot g'(x)dx=f(g(x))+c.\nonumber\]

    Esta fórmula de integración suele ser implementada por dejar\(y = g(x)\). Entonces uno escribe\(dy = g'(x)dx\) para obtener\[\begin{aligned}\int f'(g(x))g'(x)dx&=\int f'(y)dy \\ &=f(y)+c \\ &=f(g(x))+c.\end{aligned}\]
