Derivar la siguiente función $ f (x) $ usando la regla del cociente.

", "advice": "

La regla del cociente dice que si $ u $ y $ v $ son funciones de $x$, entonces
\\[\\simplify[std]{Diff(u/v,x,1) = (v * Diff(u,x,1) - u * Diff(v,x,1))/v^2}\\]

\n

Para este ejemplo:

\n

\\[\\simplify[std]{u = ({a}x+{b})}\\Rightarrow \\simplify[std]{Diff(u,x,1) = {a}}\\]

\n

\\[\\simplify[std]{v = ({c} * x+{d})} \\Rightarrow \\simplify[std]{Diff(v,x,1) = {c}}\\]

\n

Por lo tanto, al sustituir en la regla del cociente anterior obtenemos:

\n

\\[\\begin{eqnarray*} \\frac{df}{dx}&=&\\simplify[std]{({a}({c}x+{d})-{c}({a}x+{b}))/({c}x+{d})^2}\\\\ &=&\\simplify[std]{({a*c}x+{a*d}-{c*a}x-{c*b})/({c}x+{d})^2}\\\\ &=&\\simplify[std]{{det}/({c}x+{d})^2} \\end{eqnarray*}\\]
