Solution 34612: Calculating Inverse Natural Logarithms on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.

How do I calculate the inverse natural log on the TI-83 Plus and TI-84 Plus family of graphing calculators?

The following examples will demonstrate how to compute the inverse natural logarithm (or e) of a number:

Example: Compute the inverse natural log of .5.

1) Press [2nd] then [ln] to input the inverse natural log function (e)
2) Press [.] [5]
3) Press [enter] to complete the calculation



Example: Calculate the inverse natural log of 1.

1) Press [2nd] [ln] to input the inverse natural log function (e)
2) Press [1]
3) Press [enter] to complete the calculation



Please see the TI-83 Plus and TI-84 Plus Family guidebooks for additional information.
