+
+The quadratic equation for a cone describes a cone of two sheets. One sheet is a
+cone of positive slope, and the other has a negative slope. The parameter sign
+provides the option to select either of the two sheets. The +1 or the -1 entry on
+the cone surface card causes the one sheet cone treatment to be used. If the sign
+of the entry is positive, the specified sheet is the one that extends to infinity
+in the positive direction of the coordinate axis to which the cone axis is parallel.
+The converse is true for a negative entry.
