use newtons method to locate t starting with b as an initial guess.

let u=b - f(b)f'(b) denote the first approximation supplied by newtons method

which of the followin are true

1.u>b

2.u<b

3.u>a

4.u<a

5.u>t

6.u<t

7.impossible to determine

so i had

x^2=612

f(x)=x^2-612

f'(x)=2x

b=10

t=sqrt(612)

10-(10^2-612)/(2*10)=35.6

35.6-(35.6^2-612/(2*35.6)=26.395

1.u>b true

2.u<b false

im not ure what a is supposed to be
