Discussion Overview
The discussion revolves around how to delete unwanted equations from the numeric solver app on the TI-89 calculator. Participants share their experiences and seek solutions regarding the limitations of the numeric solver, particularly in managing the list of equations.
Discussion Character
- Technical explanation
- Debate/contested
- Homework-related
Main Points Raised
- One participant expresses frustration in finding a way to delete equations from the TI-89 numeric solver, noting a lack of guidance in the manual and online resources.
- Another participant suggests that the TI-89 retains 11 equations in the numeric solver and proposes that deleting a specific variable name may remove the associated equation, although they are uncertain about this method.
- A different participant mentions that while they cannot delete equations, they find that older equations drop off the list as new ones are added, indicating a potential workaround.
- One user proposes using BASIC programs to manage equations, suggesting that this could allow for more than 11 equations, although they acknowledge the method may be convoluted.
- Another participant confirms that they are unable to delete equations in the numeric solver but notes that the equations do fall off the list as new ones are added, highlighting a limitation for students with many equations.
- Instructions are provided by a participant on how to save equations in the calculator's memory for later use, detailing the steps to save and reload equations.
- One participant states that to delete a saved equation, one can use the [2nd][VAR-LINK] function, highlighting a specific method for managing saved equations.
Areas of Agreement / Disagreement
Participants generally agree that there are limitations in deleting equations from the numeric solver, and multiple views exist regarding potential methods to manage equations. The discussion remains unresolved regarding the most effective way to delete equations.
Contextual Notes
There are limitations in the number of equations that can be managed within the numeric solver, and participants express varying degrees of success with different methods for handling equations. Some methods proposed may depend on user familiarity with the calculator's features.
