Homework Statement
Using the Newton Raphson formula to calculate a solution for
[tex]x^2-8cos(x)[/tex]
Homework Equations
[tex]x_n+1=x_n-\frac{f(x_n)}{f'(x_n)}(n=0,1,2,3)[/tex]
The Attempt at a Solution
I get
[tex]x_n-\frac{x^2-8cos(x)}{2x+8sin(x)}[/tex]
Fine but how do I chose an initial term [itex]x_0=?[/itex] the book does not tell me why it has chosen the initial term in its singular example, and since it appears to be random or arbitrary :uhh:
