SUMMARY

The discussion focuses on graphing the differential equation y' = y - x + 1 using the TI Nspire CX CAS calculator. Users encountered issues inputting the function f(x) = y - x + 1, leading to no visible output on the screen. A solution was suggested to ensure that window coordinates are properly defined to display the graph. One user successfully graphed the function but faced difficulties reproducing the result after closing the document.

PREREQUISITES
  • Understanding of differential equations, specifically first-order linear equations.
  • Familiarity with the TI Nspire CX CAS calculator interface.
  • Knowledge of graphing functions and adjusting window settings on graphing calculators.
  • Basic concepts of tracing functions on graphing calculators.
NEXT STEPS
  • Research how to input differential equations on the TI Nspire CX CAS.
  • Learn about adjusting window settings for optimal graph visibility on TI Nspire calculators.
  • Explore the tracing feature on the TI Nspire CX CAS to analyze graph behavior.
  • Study first-order linear differential equations and their graphical representations.
USEFUL FOR

Students, educators, and mathematicians who are working with differential equations and using the TI Nspire CX CAS for graphing and analysis.

how do i graph y'=y-x+1 on ti nspire cx cas.
 
Physics news on Phys.org
This looks like a good reference.
 
the example they use is simple. I can't input f(x)=y-x+1 into the calculator. when i try y1=y-x+1, nothing shows up on the screen

Are you sure you have the window coordinates defined such that the plot passes through it? What happens when you trace the function?
 
I'm not sure. But I did it and the graph showed up and then I mistakenly closed the document, I didn't change any settings but I wasn't able to do it again.
