Question from kritica, a student: limit x->0 (logx-log(x-1)) |
Kritica,
To evaluate this limit you need two facts. The first about logs
log(p/q) = log(p) - log(q)
and the second about limits and logs.
If f(x) is a continuous function then lim(log(f(x))) = log(lim(f(x))) where both limits are as x approaches a.
