Instead, after f(x) and g(x) functions are created, the initial guess (0.5) is entered in the Calculate screen so Ans becomes the initial guess. After that, your suggestion to create f(Ans) and repeatedly press EXE, gives each iterate. The entire streamlined procedure is as follows: 1) From Home, highlight Calculate, click EXE and click Function. 2) Highlight Define f(x), enter e^-x, and click EXE. 3) Click Function, highlight Define g(x), click EXE, click x, and click EXE. 4) Enter 0.5, then click EXE. 5) Click Function, highlight f(x) and complete "f(" by clicking Ans and entering ")" to get "f(Ans)", select EXE and the first iterate 0.6065306597 is displayed. 6) To manually obtain subsequent iterates, click EXE repeatedly. |
