I was working on a program on my TI-92, and ended up in an endless loop, rendering my calculator virtually useless. I don't want to take the batteries out because I have way to much info in their. If anyone has any suggestions, PLEASE let me know! Thankyou. Also, does anyone have an Euler's Method or Euler's Improved Method for Differential Equations program? If so, please let me know? Thankyou. Sincerely, Dave
