A logarithm is the exponent to which a specified base must be raised to produce a given number.

The derivative of a logarithmic function can be found by applying implicit differentiation to its exponential form.

Because the exponential term equals x, it can be replaced into the differentiated equation to get the final result.

So, the derivative of a logarithmic function with base b equals the reciprocal of the product of x and the natural logarithm of b.

When the base b is e, and because the natural logarithm of e equals one, the derivative becomes the reciprocal of x. This special case is the derivative of the natural logarithm.

The reciprocal pattern means each added unit has less impact than the one before. This mathematical behavior forms the foundation for diminishing returns, a concept that appears in real-world areas such as finance.

The derivative of the logarithmic function represents the investment's rate of return, which is inversely proportional to time.

This means investments often grow faster at the beginning, no matter the size of the initial amount.
