buttons under the graph allow various manipulations of
the graph coordinates.
- The text input field for f (x) can accept
a wide variety of expressions to represent functions.
- The text input fields for c and x can accept real numbers
in decimal notation.
- The "Point Zoom" button has an effect similar
to the "Zoom In"
button under the graph,
but uses the
red point on the graph as the center of the new graph
region, so that
the "Point Zoom" button requires only one mouse
click, on the button itself, to enlarge the graph
(unlike the "Zoom In" button, which requires a
second click on the graph to determine the center point of the
new graph region).
