Hello,(adsbygoogle = window.adsbygoogle || []).push({});

The definition is [itex]ln(x) = \int_1^x\frac{1}{t}dt[/itex]

I have read several sources regarding this, but what I can't seem to find is why it was defined this way. What is the justification for defining it this way, and how was ln (x) found to be the same as the that particular integral?
