Is the derivation of this relationship ln x/y = ln x - ln y(adsbygoogle = window.adsbygoogle || []).push({});

exclusively from, and originating from the evaluation of the Integral from 1 --> x 1/t dt = ln x ?

To say another way can ln x/y = ln x - ln y always be considered to apply to this integral ?
