How do I calculate inverse logs or antilogs on the TI-89 family, TI-92 family or Voyage 200 graphing calculators? The inverse log of a number N is equal to 10^N. 10^ can be entered manually or accessed through the CATALOG menu.
The examples listed below will display how to calculate the inverse natural log on the TI-89 family, TI-92 family or Voyage 200 graphing calculators. Example 1: Find the inverse natural log of 1.60944
Try taking the log (not ln) of 24989.8757657. That will tell you the power you need to raise 10 to to get it. By the way, an inverse log is simply 10 raised to whatever power you want the...

22 lut 2009 · A logarithm is the inverse function to exponentiation. It is used to solve equations involving exponential expressions, such as taking the power to which a base number must be raised to produce a given number.
Overview of the TI-89 (TI-92 Plus, Voyage 200) This chapter provides a brief introduction to some of the features of this family of graphing/symbolic calculators that relate to pre-calculus material. For the most part, we demonstrate with the TI-89 (including the TI-89 Titanium), which is the most common choice
The TI-89 will graph the natural logarithm, y=ln x, and the common logarithm, y=log x. However, graphing functions in other bases requires the use of the Change of Base Property. 1. Natural Logarithms and Common Logarithms.
