F2 3:Newton’s Method
Displays the problem-entry dialog box for Newton's Method
along with an example problem. Enter a function
f
(
x
), Initial
guess, and Number of iterations.
Note
The number of iterations must be an integer

1.
The solution appears in a split screen. One portion of the split
screen displays a sequence of approximations to a real root
of the functions.
The other portion of the split screen displays a graph of the
function and draws tangent lines corresponding to
consecutive iterations.
The application draws the first guess for you. Press either
¸
or
N
to view the consecutive guesses. This example
shows four iterations.
