General feedback
Aquesta funció és el quocient de dues funcions, per tant, el seu límit en un punt és igual al quocient dels límits d'aquestes funcions en el punt (sempre que el denominador no sigui 0). És a dir, <br /><br />Si <span class="nolink">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«munder»«mo largeop=¨true¨»lim«/mo»«mrow»«mi»x«/mi»«mo»§#8614;«/mo»«mi»a«/mi»«/mrow»«/munder»«mi»g«/mi»«mo»(«/mo»«mi»x«/mi»«mo»)«/mo»«mo»=«/mo»«mi»b«/mi»«/math»</span> i <span class="nolink">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«munder»«mo largeop=¨true¨»lim«/mo»«mrow»«mi»x«/mi»«mo»§#8614;«/mo»«mi»a«/mi»«/mrow»«/munder»«mi»h«/mi»«mo»(«/mo»«mi»x«/mi»«mo»)«/mo»«mo»=«/mo»«mi»c«/mi»«/math»</span> llavors <span class="nolink">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«munder»«mo largeop=¨true¨»lim«/mo»«mrow»«mi»x«/mi»«mo»§#8614;«/mo»«mi»a«/mi»«/mrow»«/munder»«mfrac»«mrow»«mi»g«/mi»«mo»(«/mo»«mi»x«/mi»«mo»)«/mo»«/mrow»«mrow»«mi»h«/mi»«mo»(«/mo»«mi»x«/mi»«mo»)«/mo»«/mrow»«/mfrac»«mo»=«/mo»«mfrac»«mi»b«/mi»«mi»c«/mi»«/mfrac»«/math»</span><br />Si el límit del denominador és 0, llavors el límit és infinit i cal calular els límits laterals per a establir-ne el signe.<br />
