Calculation of limit. L'Hopital's rule

[QUOTE="EEristavi, post: 5775868, member: 618397"] [B]Problem: Evaluate lim(x->0) x cotx[/B] [B]My attempt:[/B] lim(x->0) x cotx = lim(x->0) x cosx / sinx = lim(x->0) cosx * lim(x->0) x / sinx = 1 * lim(x->0) x / sinx = lim(x->0) x / sinx [B]P.S.[/B] I know I must/can use L'Hopital's rule to evaluate indeterminate limits, but no matter how many times I derive x/sinx I will always have sinx (in some power) in denominator. I also tried different grouping of variables but still same scenario. maybe I don't see something so even little hint would be nice... [/QUOTE]
