Newton's Method
Equation:   Guess:

xMin = xMax =

yMin =
yMax =

Enter the expression that you want to find the zeros of and enter your guess.  Then hit the submit button to explore how Newton's method works.

You can choose the x and y constraints and the size of the graphing rectangle as follows:

• zIn: This will zoom in with the center at the root and the scale one fourth the size of the current scale.

• zOut:  This will zoom out with the center at the root and the scale four times the size of the current scale.

• zBox:  This will allow you to drag your mouse on the xy-plane to draw the rectangle that will be the new graphing rectangle.

• zStd:  This make the viewing bounds for both x and y go from -10 to 10.

• Trace:  This allows you to move your mouse over the graph and see the x and y coordinates on that point on the graph.

•  The Width and Height controls make the rectangle bigger or smaller on your screen.  Std puts it back to where it was when the program started.
