The TI 86 has two logarithmic functions: natural logarithm **(ln) **and common (decimal) logarithms **(log)**. If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions

**log_b(x) =ln(x)/ln(b) =log(x)/log(b)**

Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.

**Note:** On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.

Use the equivalent formula log base b of a is equal to [log10(a)]/[log10(b)], you can also use ln(a)/ln(b), the results will always be equivalent

There is no common logarithm function on this calculator. However, you can calculate it easily enough using the natural logarithm function (ln). The log of x is equal to ln(x) / ln(10). In words, calculate the log of a number by calculating its ln then dividing by ln of ten.

you can press the "**log" **button or the **"ln" **for logarithmic calculations. the difference is just that "ln" calculates log on base "e".
