**Reiny**, Monday, November 10, 2008 at 11:44pmlet f(x) = x^5+x-6

newton's method says

x_{n+1}= x_{n}- f(x_{n})/f'(x_{n})

f'(x) = 5x^4 + 1

so x2 = x1 - f(x1)/f'(x1)

= 2 - 28/81

= 1.65432

then x3 = 1.65432 - .209237

= 1.44508

x4 = 1.3685

x5 = 1.35942

x6 = 1.359304105

x7 = 1.359304086

x8 = 1.359304086 Ok then !!!
