I want to make the following recursive function: xm+1 = xm - F(x)/F'(x)
so I did this:
"X="?->X
"F(X)="?->A
"F'(X)="->B
Lbl 1: X-(A)/(B ) -> X (display)
Goto 1
so at starting the program
for a function like xm+1 = xm - (xm^3 -100)/(3*xm^2)
I introduce
4
X^3-100
3*X^2
But when the program makes the second iteration it doesn't changes the X paramater from functions A and B
so, at the first iteration gives
4.75, but at the second gives 5.5 instead of 4.644044!
How can I do what I want then?
Thanks
