Increasing Precision of 3D plots

When you look at the previous graph, it seems that the resolution of the graph is not very high. To decrease the amount of choppiness in the graph, you need to increase the precision used. This can be done for 2D plots by the set samples command, and for 3D plots by set isosamples command. You will almost always have to use this for 3D plots, because the default sampling rate is very low. The syntax of the command is: The default is for both rates to be set to 10. For example, typing the following yields:

It is important to note that the higher you set the isosamples, the longer it will take to create the graph. In most cases, you won't want to set the sample size larger thant 100.
