L Scale And Negative Logs With Applications Youtube In this video i discuss how to compute logarithms of numbers less than 1 on the slide rule by imagining that the l scale runs backwards. i demonstrate the te. Ph (chemistry): concentration of hydrogen ions converted into negative (common) logarithm. increase ph by $1$ decreases the acidity of a solution by tenfold. richter scale (seismology): relative seismic wave amplitude converted into common logarithm. one unit of increase in richter scale increases the severity of an earthquake by tenfold.
Come Leggere Una Scala Logaritmica 10 Passaggi Enhance your understanding of logarithmic functions and their practical applications through this detailed resource. explore the rules, formulas, and real life examples of the laws of logs, empowering you to confidently manipulate logarithmic expressions. With logarithms a ".5" means halfway in terms of multiplication, i.e the square root (9.5 means the square root of 9 3 is halfway in terms of multiplication because it's 1 to 3 and 3 to 9). taking log (500,000) we get 5.7, add 1 for the extra digit, and we can say "500,000 is a 6.7 figure number". try it out here:. Logarithmic scale. a logarithmic scale (or log scale) is a method used to display numerical data that spans a broad range of values, especially when there are significant differences between the magnitudes of the numbers involved. unlike a linear scale where each unit of distance corresponds to the same increment, on a logarithmic scale each. One still might want to represent several different orders of magnitude on both positive and negative axes, or possibly deal with zeros when the differences between those values is not as important. one solution that people sometimes use is a pseudo log transform: x => sign(x) * log(1 abs(x)). this function does have a pitfall, however, of not.
