Given information
According to the question with help of Newton's method for approximating a root of the equation , and from an initial approximation we can obtain successive approximations , where
Step-by-step explanation
Step 1.
Taylor's Inequality is:
With and , it takes the form:
Now we need to find , it is defined as
Next step is to write the first order polynomial at
now becomes:
Substitute and
The problem states that is a root of meaning :
Now transforming Newton's equation, we achieve:
We plug this in :
Take its absolute value :
Finally we know that so let's take to be the smallest value it can be:
Final form of is:
Plug it in Taylor's Inequality:
