Welcome to the world of graphing calculators.
Quick-Start is not a complete tutorial, but it takes you through many of the most common
functions, from turning the power on, and on to graphing complex equations. When
you’re done, you’ll have mastered the basic operation of this calculator and will be ready
to proceed with the rest of this user’s guide to learn the entire spectrum of functions
available.
Each step of the examples in Quick-Start is shown graphically to help you follow along
