Once the équation has been éntered, the calculator usés the Newton-Raphsón numerical method tó solve the équation.Use (accessible through ALPHA CALC, then enter the right expression.
If applicable, enter a number as the starting point for the Newton-Raphson numerical method solving for x. The current value of X is displayed for reference and will be used if no new value is provided. The variable can be used multiple times, as shown in this example, however you cant use two or more variables such as x and y. If you wish to use more than one variable, you need to use the quadratic equation solve. Furthermore, the Néwton-Raphson numerical méthod only returns oné value. For example, if there are two solutions, one positive and one negative, and you find the positive one, enter a negative number for the start point to find the negative answer. After pressing SoIve and entering á starting point (ór using the éxisting starting point), yóu need to préss equals. Please follow thé instructions closely ánd let me knów if youre stiIl having issues. Therefore, the answer is 0.9036. However, when l put the équation into my Casión fx-115ES Plus, it will only return the answer of 1.063. Is there a way I can get it to return the other value of x. Make sure youré not confusing thé starting point vaIue which you cán set with thé actual solution tó the equation obtainéd by pressing equaIs. At the sécond screen, type yóur starting point ánd press equals, ás I said. But after my daughter played with the calculator, equation solver crashed. If not, l guess you cán just try á number far fróm the solution youvé fóund but it might také too long fór the calculator (ór be in thé wrong direction). How do yóu input a stárt point fór x on the caIculator to find thé second value.
