Plotting Applet
Simple Plot Applet
Instructions:
- Click the "f(x)=" button to define function. x2
="x^2" is the default.
- When entering functions, make sure the variable is surrounded by "()"'s,
e.g. exp(x^2) should be written as exp((x)^2) for the parser to work correctly.
- If you want to enter two functions, type in a function e.g.
"sin(x)", then press "f(x)=" again. You can
also enter a comma separated list of functions. This is useful if you want to
find the intersection of two functions. The coordinates of the
lower left and upper right corners are displayed.
- To shift the applet, select the "Shift" button. You are given
four choices, left, right, up or down. The function argument is
changed appropriately, and the new function is displayed at the top of
the plot. You can set the shift amount in the textbox to the
right of the shift buttons.
- To zoom in the mid point of the canvas, select "Zoom". You have
two options: in or out.
- "Clear" removes all the functions.
- "Reset" resets the range and domain and scale.
- Dragging the mouse graphs a sub rectangle
- The axes and/or function graphs can be "dragged" with the mouse.
- The applet is resizeable, in the sense that if you resale
the window, and reload, it scales to the siz of the visible
window...
Note: We can add as many buttons, with sub options, as we want
