# In Problems 1-12, find the derivative of each function. y = ln  x x

To determine

To calculate: The derivative of the function y=lnxx.

Explanation

Given Information:

The provided function is:

y=lnxx

Formula used:

The derivative logarithmic function:

ddx(lnx)=1x

The quotient rule of derivatives:

ddx(u(x)v(x))=v(x)ddxu(x)u(x)ddxv(x)[v(x)]2

Calculation:

Consider the provided function:

y=lnxx

Differentiate both sides with respect to x as:

dy
