:log(value)

returns the base 10 logarithm of a value. This is the inverse function of 10^(

(84)(89) :log(value,base)

Returns the log of a certain value to a certain base. Note that this only works when you have a calculator with OS 2.53 or higher.

LocationEdit

  • LOG

Examples Edit

  • \log{100}
    • The above equation would give you an answer of 2, because 102=100.
  • \log{1}
    • The above equation would give you an answer of 0, because 100=1 (any number to the power of zero is 1).

Change of BaseEdit

Just because only log10( and ln( are the only log functions on the TI-84 calculator does not mean that those are the only two bases logs can be found for. As per the change of base property of logs, if one wanted to find \log_2{8}:

  • \frac{\log{8}}{\log{2}}
    • The above equation would give you an answer of 3, because 23=8, and \frac{\log{8}}{\log{2}} is equivalent to \log_2{8}.
    • If you prefer, \log{2}≈.301 and \log{8}≈.903, and \frac{.903}{.301}=3
