  1. Symbolic view improvements
  2. Plot view improvements
  3. Numerical view improvements


  1. Symbolic view improvements
  2. Plot view improvements


  1. Plot view improvements: Ability to pinch/zoomin the X direction only or Y direction only. Ability to sketch afunction directly of the types exp, ln, sin, x^2, linear.

New Functionality:

  1. Added more distribution functions – density/cumulative/inverse: beta, exponential, gamma, geometric, negbinomial, uniform, weibull
  2. Added more random generation functions: binomial, chisquare, fisher, geometric, poisson, student
  3. Added functions DDAYS, DATEADD, DAYOFWEEK
  4. Added application variables AFiles, AFilesB and DelAFiles. Allows direct access of application specific files
  5. Added variables HVars and DelHVars. Allows direct creation and access of home variables
  6. Added application variables AVars and DelAVars. Allows direct creation and access of application specific variables
  7. Applications now individually contained inside a directory structure to group variables and files together
  8. Sequence application can start at a location from 0-1000. Less stringent checking of recursion to allow things like U1(U2(N-1))
  9. Improved on-calculator DEBUG interface
  10. Added ability for title and display only in EDITLIST and EDITMAT

  16. Added MEMORY command to allow programs to check space
  17. Added UPPER and LOWER string commands to convert case
  18. Added display of G0-G9 in history
  19. Added ability to use + and – keys directly for one directional limits
  20. Added ability to use non-real inputs in the program catalog RUN menu
  21. Added clear confirmation on programs and note editor

Resolved issues and changes excluding CAS:

  1. Resolved issue with local variable initialization in a program with using a complex number
  2. Renamed “Program” and “Note” into “AProgram” and “ANote” to distinguish better from variables “Programs” and “Notes”
