I've been graphing space curves for my calculus class and have encountered an anomaly. On a machine in one lab, I enter the curve as a vector, eg [t,t^2,t^3], open a three-d plot window, click on INSERT, then on PLOT. I get the dialog box allowing me to enter minimum and maximum values of the parameter t as well as the number of panels. I then get the plot as I requested it. On a machine in a second lab, the values I enter for minimum and maximum values of the parameter as well as for the number of panels are ignored and I get a graph apparently generated from some set of "default" values. Interestingly enough, the machine in my office behaves in the manner of the first lab machine and the one on my desk at home in the manner of the second. Has anyone encountered this? Do we have two versions of DERIVE running? Is there some setting on one set of machines that can be changed to eliminate the problem? Thanks in advance.
