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.
