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.
