lim(x->0) (sinx)^n/sin(x^m)
=lim(x->0) x^n/x^m
=lim(x->0) x^(n-m)
case 1: n>m
lim(x->0) (sinx)^n/sin(x^m)
=lim(x->0) x^(n-m)
=0
case 2: n=m
lim(x->0) (sinx)^n/sin(x^m)
=lim(x->0) x^(n-m)
=1
case 3: n<m
lim(x->0) (sinx)^n/sin(x^m)
=lim(x->0) x^(n-m)
->∞

lim(x->1) sin(x^2-1)/(x-1) (0/0)
=lim(x->1) 2x.cos(x^2-1)
=2
