__Logarithms on the Graphing Calculator__

A **graphing calculator** is a handheld device that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. **Graphing calculators** are generally programmable. So the user can create customized programs for science, engineering and education applications. Because they have large displays, it can display several lines of text and calculations at the same time. On using the **graphing calculator** the goal is to be able to turn the **graphing calculator** on and off and also to cover how to enter various expressions on the **graphing calculator** including fractions, exponents, radicals, scientific notation, evaluating expressions, matrices, logarithms and regression. **Graphing logarithmic functions** on **TI-84s **isn't much different from graphing any other functions. You just hit your **"Y="** button an enter your equation. The only complication occurs when you have a **log** with a base other than **10 **or** e .** To do this, just go to your **"Math"** key, and scroll down till you find **"LogBase".**
