Aplet variables To access an aplet variable Most aplet variables store values that are unique to a particular aplet. These include symbolic expressions and equations (see below), settings for the Plot and Numeric views, and the results of some calculations such as roots and intersections. See the Reference Information chapter for more information about aplet variables. Category Function Parametric Polar Sequence Solve Statistics Available names F0 to F9 (Symbolic view). See "Function aplet variables" on page R-7. X0, Y0 to X9, Y9 (Symbolic view). See "Parametric aplet variables" on page R-8. R0 to R9 (Symbolic view). See "Polar aplet variables" on page R-9. U0 to U9 (Symbolic view). See "Sequence aplet variables" on page R-10. E0 to E9 (Symbolic view). See "Solve aplet variables" on page R-11. C0 to C9 (Numeric view). See "Statistics aplet variables" on page R-12. 1. Open the aplet that contains the variable you want to recall. 2. Press to display the VARS menu. 3. Use the arrow keys to select a variable category in the left column, then press in the right column. to access the variables 4. Use the arrow keys to select a variable in the right column. 5. To copy the name of the variable onto the edit line, press . ( is the default setting.) 14-8 Variables and memory management
