Discussion Overview

The discussion centers around the capabilities of graphics calculators in solving simultaneous equations that include trigonometric functions with variables, such as cos(x). Participants explore different models and functionalities of various calculators in this context.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about graphics calculators that can solve simultaneous equations involving trigonometric functions.
  • Another participant claims that their TI-89 and TI-92 calculators can handle such equations easily.
  • A different participant describes limitations with their Casio calculator, noting that it only allows substitution of numerical values into a standard form and produces an error when attempting to input functions like cos.
  • Another approach mentioned involves using matrix operations and the reduced row echelon form function to solve simultaneous equations, questioning whether this feature is available on the calculators discussed.

Areas of Agreement / Disagreement

Participants express differing experiences with various calculators, indicating that there is no consensus on the capabilities of graphics calculators for this specific task.

Contextual Notes

Limitations include the specific functionalities of different calculator models and the potential for misunderstanding how trigonometric functions can be incorporated into simultaneous equations.

Does anyone know of a graphics calculator that can solve simultaneous equations that have trigonometric functions with variables ie. cos(x)?
 
Computer science news on Phys.org
I think most graphing calculators can do this easily. My TI-89 and TI-92 can.
 
on my casio the simultaneous equation solver just let's you sub a, b, and c values into
anX+bnY=Cn and if you just try subbing a function such as cos into one of them it says Syn error. Does it work in a similar way on your calculator or are you able to just type in the whole equation?
 
When solving simultaneous equations I normally use an approach utilizing a calculator's ability to handle matrices, and the reduced row echelon form function, rref(. Can yours do that?
