WebThe logs of negative numbers (and you really need to do these with the natural log, it is more difficult to use any other base) follows this pattern. Let k > 0. ln (−k) = ln (k) + π 𝑖. For other bases the pattern is: logₐ (−k) = logₐ (k) + logₐ (e)*π 𝑖. If you mean the negative of a logarithm, such as. y = − log x, then you ...
