Use the bisection method to find a root of the function

Using JKGraph:

Since *f(0) > 0* and *f(1) < 0*, we use the bisection method
on the closed interval [0,1].

- On the
*Formulas*menu, choose*Function Formula: Y=F(X)*. - At the prompt
*F(X) =*, type incos(x)-x - Click on the button
*Edit Solve Domain*. - At the prompt,
*First Point X-Coordinate:*, enter 0. - At the prompt,
*Second Point X-Coordinate:*, enter 1. - At the prompt,
*Solution Method*, click on*Successive Bisections*. - At the prompt,
*Output Format*, click on*Graphical Output*. - At the prompt,
*Automatic/Manual*, click on*Automatic Animation*. - Click on the
*OK*button. - Click on the
*World Graph Domain*button. - At the prompt,
*Graph X Minimum Value:*, enter 0. - At the prompt,
*Graph X Maximum Value:*, enter 1. - At the prompt,
*Graph Y Minimum Value:*, enter -1. - At the prompt,
*Graph Y Maximum Value:*, enter 1. - Click on the
*OK*button twice and you will see the graph of the function. - Finally, click on the
*Solve*button and you will see the following graph.The approximation of the root appears at the bottom of the screen.
