    16-2 Inputting a Recursion Formula and Generating a Table Example 1 To input + 1 and generate a table of values as the value of change from 1 to 6 Make = 1. 1. Specify the recursion formula type as linear recursion between two terms and then input the formula.
  • Page 4 16 - 2 Inputting a Recursion Formula and Generating a Table 4. Display the table of the recursion formula. At this time, a menu of table functions appears at the bottom of the screen. J6(TABL) Currently selected cell (up to six digits) Value in currently highlighted cell •...
  • Page 5 16 - 2 Inputting a Recursion Formula and Generating a Table The table range settings specify the conditions that control the value of variable the recursion formula, and the initial term of the numeric value table. Start ....Starting value of variable End ....
  • Page 6 16 - 2 Inputting a Recursion Formula and Generating a Table • Changing the angle unit setting while a table generated from a trigonometric expression is on the display does not cause the displayed values to change. To cause the values in the table to be updated using the new setting, display the table, press 1 (FORM), change the angle unit setting, and then press 6 (TABL).

    16-3 Editing Tables and Drawing Graphs You get a choice of four options for editing tables and drawing graphs. • Deletion of a recursion formula table • Drawing of a connect type graph • Drawing of a plot type graph •...
  • Page 9 16 - 3 Editing Tables and Drawing Graphs k k k k k Before Drawing a Graph for a Recursion Formula You must first specify the following. • Draw/non-draw status of for the recursion formula • The type of data to be plotted To specify the draw/non-draw status, display the Recursion Menu and then press 1 (SEL).
  • Page 10 16 - 3 Editing Tables and Drawing Graphs (Draws graph with on the vertical axis.) Example 2 Draw a graph of + 1 with on the vertical axis and on the horizontal axis, and with the points unconnected. Use the same View Window parameters as those provided in Exam- ple 1.
  • Page 11 16 - 3 Editing Tables and Drawing Graphs This example assumes that the following two recursion formulas are already stored in memory. 1 2 3 4 5 1. Press 6 (TABL) to generate a table. 6(TABL) 2. Press 4 (WEB) to draw the graph. 4(WEB) 3.
  • Page 12 16 - 3 Editing Tables and Drawing Graphs This graph indicates that recursion formula = –3 is convergent. Example 2 To determine whether or not the recursion formula + 0.2 is convergent or divergent. Use the following table range. Start = 0 = 0.02 Str = 0.02 Use the View Window parameters from Example 1.
  • Page 13 16 - 3 Editing Tables and Drawing Graphs 3. Each press of w draws web-like lines on the display. This graph indicates that recursion formula + 0.2 is divergent. • Inputting for the expression , or Inputting for the expression for linear recursion between two terms causes an error.
