At the same time you will learn the corresponding basic techniques of using DERIVE. Start DERIVE. Your first session with DERIVE left a trace in the form of an initialization file. This file stores information about the status of DERIVE before you last shut it down. For example, the change performed with the Options>Display>Font of New Text Objects command is among the data in this file. The Derive Startup dialog gives you the choice to either start DERIVE with the factory default settings or start DERIVE with the settings from the initialization file, i. e. This book is written so that each chapter starts with a factory default DERIVE. Start with a factory default DERIVE by exiting the dialog with (_Yes_). Insert a text object containing the text "Finding the zeros of a polynomial. " You will look for the zeros of the polynomial y = p( x) , y = x 4 3x3 5 x 2 7 x 1 + - - -.
