Best ResponseYou've already chosen the best response.0You can use l'Hopital's rule whenever you have a limit which comes out to be 0/0 or infinity/infinity and has the form " lim f(x)/g(x) ".

Best ResponseYou've already chosen the best response.0ok so in this case you have to use l'hopitals rule which will getyou sin(5x) der is 5cos(5x) sin(4x) der is 4cos(4x) so you will end up wit limit as n  > 0 of 5cos(0)/4cos(0) = 5/4
