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.
Learning Outcomes: Visualize the geometry and calculus of Newton's Method
