It has many wonderful properties, such as the derivative of lnx itself.

Main applications: 1+lnx ≤ x, (x > 0), when x= 1, etc.

In fact, lz has known since I entered high school. It's a common thing, but I admire the landlord's spirit of exploration. I knew nothing about these things before I entered high school.
