The logs and trig calculator has been designed to convert between logs and antilogs, and between plain and hyperbolic trigonometric values and their inverses.
Your logarithmic conversions can be of any base greater than zero (except 1) and LogTrig holds default values for the common log base of 10 and the natural log base of 2.71828182845905
You can enter your angles in radians or degrees and LogTrig will automatically convert to and provide results in both forms simultaneously. All six associated results (see Calculation Options below) are calculated and displayed simultaneously. The logs and trig calculator will let you know which (if any) cannot be converted from your input data.

Logs & AntiLogs
You enter a number and a Base and LogTrig will convert the number to a logarithm of the Base entered. Unless you enter a valid Base, LogTrig will default to a Base of 10
