[@felipesb2]

Thank you, I was wondering how to do this on my fx991 for days. This will be useful when we are using bisection, secant method or even a illinois method (modded false position), because we need to calculate the f(x) values in each iteration to decide the new interval comparing their f(x) values... But, for newton raphson you can use the "ANS" button trick... I think it is faster than doing like you did. Here's the trick: First, you save your X0 on ASN (just insert X0 on calc and press equal sign) Then you insert the newton expression using ANS in the X0 place... ANS - f(ANS)/f'(ANS) e.g.: f(x) = x² + 2 Newton expression to put in calc: ANS = 0 (first value) Then insert ANS - (ANS² + 2)/(2ANS) Then just press equal sign how many times you want... You can use this ANS trick also in the "false position method" when you find out which of the terms in the interval is fixed... and also in the "fixed point method"

[@sonakshi.3542]

Thanks a lot... your trick is extremely helpful 😁

[@shramanshraman5928]

In place of "X" if you keep "Ans" and keep pressing "=" it becomes even simpler...

[@melvinhenera6217]

Hi Sujoy. There is another method to achieve roots of equation: [MODE] > [5: EQN] > [3] (for quadratic equation) Input a: 1, b: 2, c: -2 a represents the coefficient for X^2 b represents the coefficient for X it will give you: X1: 0.7320508076 X2: -2.732050808 Try it. :D

Answer I have one more question the value of x that I have two assumed it from zero to +3 and from 0 to-3 I mean is this is the maximum values? And how I choose the right x ?

try this question x^3-3x+1=0 this question gives the different result from calculator and the newton rapshon method this question is from b.s. grewal exercise 2.5 1question

You are great!
