Mathematically, this is expressed as d/dx [ln(x)] = 1/x. Consequently, the derivative of ln(g(x)) is g'(x) / g(x), provided that g(x) is positive.

This method showcases the deep inverse relationship between the exponential and logarithmic functions. This preference stems from the fact that the limit definitions and integral properties are significantly simplified when the base is e, eliminating the need for an extraneous constant factor in the derivative.
Since e^y is equivalent to x, solving for dy/dx immediately reveals that the derivative is 1/x. The natural log function is strictly increasing but concave down, meaning its slope is always positive yet gradually flattens as x increases.

Comparison with Other Logarithmic Bases A frequent point of confusion arises when comparing the natural logarithm to logarithms with other bases, such as base 10. By setting y = ln(x), we can rewrite the relationship in exponential form as e^y = x.
