Witryna17 lut 2024 · The numpy.log () function is a mathematical function that helps the user calculate the natural logarithm of x, where x belongs to all the input array elements. The natural logarithm log is the inverse of the exponential function, so log (exp (x)) = x. The natural logarithm is the logarithm in base e. WitrynaThe 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 ...
