How do log functions work
WebA natural logarithmic function is a logarithmic function with base e. f (x) = log e x = ln x, where x > 0. ln x is just a new form of notation for logarithms with base e.Most calculators have buttons labeled "log" and "ln". The "log" … WebA logarithmic function is a function of the form. which is read “ y equals the log of x, base b ” or “ y equals the log, base b, of x .”. In both forms, x > 0 and b > 0, b ≠ 1. There are no restrictions on y . Example 1. Rewrite each exponential equation in its equivalent logarithmic form. The solutions follow.

WebNov 4, 2016 · log W T = ∑ t = 1 T r t where r t = log ( 1 + R t) = log W t − log W t − 1. Where are percent changes and the log difference NOT the same? For big percent changes, the log difference is not the same thing as the percent change because approximating the curve y = log ( x) with the line y = x − 1 gets worse and worse the further you get from x = 1.
