Find the Derivative - d/dx ( natural log of x)/x

Problem

d()/d(x)ln(x)/x

Solution

1. Identify the rule needed for the derivative of a quotient, which is the quotient rule: d()/d(x)u/v=(vd(u)/d(x)−ud(v)/d(x))/(v2)

2. Assign the numerator and denominator functions: u=ln(x) and v=x

3. Differentiate the individual components: d(ln(x))/d(x)=1/x and d(x)/d(x)=1

4. Substitute these values into the quotient rule formula:

(x⋅1/x−ln(x)⋅1)/(x2)

5. Simplify the numerator by multiplying x and 1/x

(1−ln(x))/(x2)

Final Answer

d()/d(x)ln(x)/x=(1−ln(x))/(x2)
