**
Write and Plot a Function
**

Works much better with MS Internet Explorer 3 and higher

The above applet combination allows you plot any function and
change the attributes of your graph. One can enter the function into
the command line below. It must be of the form y = ...,
thus y + x = 5 is not allowed. An array of functions is available,
including trigonometric, logarithmic, and exponential.
There is also a random number generator **rand**.
Note that the arguments of functions must be
in parentheses (ex: **y=sin(x)**).
One can change the starting x value **xmin** in the
command line below. The maximum x value **xmax** is entered just below
that. The number of points **numpoints** determines how accurately the
graph looks. Beware that large numbers may slowdown system
performance. The y values of the graph are scaled automatically, so
note that entering an infinite function i.e.,
**y = tan(x)**
results in a
huge y value. Also note that angle values for trigonometric functions
are entered in radians.
