Discussion Overview

The discussion revolves around an issue with the TI-89 Titanium calculator, specifically regarding unexpected outputs when performing factorization and other operations. Participants explore potential causes and solutions related to variable storage and calculator settings.

Discussion Character

  • Technical explanation, Problem-solving, Meta-discussion

Main Points Raised

  • One participant reports an unexpected output when entering a factorization command, suggesting a malfunction or misconfiguration of the calculator.
  • Another participant provides a link to Wolfram Alpha as a comparison for expected results.
  • A participant notes that similar issues arise when integrating or differentiating functions, indicating a broader problem with the calculator's output format.
  • One participant suggests that the issue may stem from a stored value assigned to the variable x, proposing a method to clear variables to resolve the problem.
  • A later reply confirms that clearing the variables resolved the issue, indicating that variable storage can affect calculations.
  • Another participant expresses shared experience with similar issues related to variable storage on the calculator.

Areas of Agreement / Disagreement

Participants generally agree that the problem was related to stored variables, and the solution of clearing variables was confirmed effective. No significant disagreement is noted.

Contextual Notes

Limitations: The discussion does not explore other potential causes for the calculator's behavior or the implications of different mode settings. Specific steps for clearing variables are not detailed.

There is something wrong with my TI-89 Titanium. When I enter factor(x^2-5x=6), it displays the answer as 6.17481 E12/ (2)^11 * (5)^13.
I've checked all the mode settings and they seem to be same as the initial settings. Any idea what could be wrong?
 
Computer science news on Phys.org
It displays answers in numerical values instead of answers with variables when I try to integrate or differentiate functions too. It has never happened before.
 
The problem seems to be that you have stored some value to x. What you may need to do is clear all those variables (there is an option from the homescreen under F1, I believe). Basically, you may have done something like this:

37→X

So then factor(x^2-5x=6) would do something like this in the background:
(x+1)(x-6)

But when it displays it, since x has an actual value, it computes (37+1)(37-6). In your case, x is clearly not 37, but I am sure you get the idea XD
 
Yes, that's it! I cleared all the variables and it works fine! Thank you very much! <3
 
That is great to hear! That is a problem that always trips me up, too, because I like to store values to variables.
