Find the Derivative - d/dx f(x) = natural log of 1/x

Problem

d(ln(1/x))/d(x)

Solution

1. Apply logarithmic properties to simplify the expression before differentiating. Use the rule ln(1/a)=−ln(a)

ln(1/x)=−ln(x)

2. Apply the constant multiple rule to move the negative sign outside the derivative.

(d(−)*ln(x))/d(x)=−d(ln(x))/d(x)

3. Differentiate the natural log using the standard rule d(ln(x))/d(x)=1/x

−d(ln(x))/d(x)=−1/x

Final Answer

d(ln(1/x))/d(x)=−1/x
