Function Log Plots


This form allows you to create a Java applet to plot up to six functions that depend on up to four parameters. The functions are displayed using a natural log vertical axis. Applet names must not contain any spaces or special characters. There are no length restrictions. Both upper and lower case characters are permitted, as are numbers.

Name of the applet

Enter the names and initial values of up to four parameters (optional).
Name: Value:
Name: Value:
Name: Value:
Name: Value:


Enter the lower and upper bounds for the independent (time) variable.

Lower Bound: Upper Bound:

Enter the lower and upper bounds for the dependent variable.

Lower Bound: Upper Bound:

Next, enter the functions you want to plot. Observe that the independent variable is always called "t". The usual complement of intrinsic functions are available. In addition, the heaviside function is available, i.e. heaviside(t)=0 if t<0, and =1 if t>0. The following are examples of acceptable function entries.
fct(t)=t^2+1
myvalue(t)=sin(2*t)
harry(t)=heaviside(t-2)+exp(-2*t)
The following are unacceptable function entries.
t^2+1
f(x)=sin(2*x)
harry=x
Each function must have a different name - e.g. f(t)=..., f1(t)=..., etc. For each function you enter, you may specify a color.





Note that you will have to change the name of your applet if this is a second submission. Netscape caches Java applets, and cannot be made to load the same applet a second time. Thus if you are modifying your existing applet, you will need to give the modified applet a new name.
