Although not completely practical and far from perfect, one could manipulate convergence condition within the iteration loop to obtain an approximate answer, or perhaps re-run the program with a different initial guess if no convergence is obtained. I am guessing OP is reluctant to use Excel or alike because it is not allowed in the exam, whereas his calculator is. | |

(convergebce condition |f.f''| < (f')^2 ) | |
| Feb 3, 2023 at 17:02 | comment | added | Sam202 | You could try making a program in your calculator using Newton's method (Jacobian matrix iteration) with an initial guess. I made one for a TI-84 calculator some years ago (older version of your calculator), so it should be a little easier in your case. | |
