The natural logarithm function
WebMar 24, 2024 · Logarithms Ln is the notation used in physics and engineering to denote the logarithm to base e, also called the natural logarithm, i.e., The United States Department of Commerce recommends that the notation be used in this way to refer to the natural logarithm (Taylor 1995, p. 33). WebLet’s take a look at a few examples to solidify our understanding of the LOG function. Example 1: Finding the Natural Logarithm. Let’s say we have the number e^4 in cell A1. We want to find the natural logarithm of this number. Our formula would look like this: =LOG(A1) And the answer is… 4! (Since e^4 = ~54.6 and ln(54.6) = 4)

WebIn mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as For x > 0 , a > 0, and a ≠1, y= log a x if and only if x = a y Then the function is given by f (x) = loga x The base of the logarithm is a. This can be read it as log base a of x.
