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.
