SUMMARY

The TI-89 calculator is not differentiating functions correctly, as evidenced by the output of a list [6 8 10] instead of the expected derivative, such as 2x for the function d(x^2,x). This issue may stem from the calculator's settings, which may not be configured to produce symbolic derivatives. Users are advised to check the calculator's mode settings to ensure it is set to compute derivatives correctly. Alternatively, Wolfram Alpha is recommended as a reliable online tool for differentiation and other mathematical computations.

PREREQUISITES
  • Understanding of symbolic differentiation
  • Familiarity with TI-89 calculator settings
  • Basic knowledge of calculus concepts
  • Experience with online computational tools like Wolfram Alpha
NEXT STEPS
  • Check the TI-89 calculator mode settings for symbolic differentiation
  • Learn how to use Wolfram Alpha for calculus problems
  • Explore TI-89 user manuals for troubleshooting differentiation issues
  • Research common issues with TI-89 calculators and their solutions
USEFUL FOR

Students, educators, and anyone using the TI-89 calculator for calculus who need assistance with differentiation and troubleshooting calculator settings.

Hello,

If i try to differentiate any function even simple function on the ti89 such as d(x^2,x) it spits out a list [6 8 10]
Can someone please help me with the calculator?

It could be that your calculator is not set up to produce function like derivatives such as 2x, and will only produce a list of values on the curve of the derivative. Or it could be that there is a mode in which to do what you want, and you have to switch to it.

Might I suggest you use Wolfram-Alpha on the internet for these and other computations. It is very comprehensive and always in the right mode.
