sections parallel to that plane being hyper-bolas with the transverse axis parallel to OX. It may also be shown that every plane through OX cutsthis surface in an hyperbola with its transverse axis on OX. The surface is a biparted hyperboloid, or hyperboloid oftwo sheets, having OX as its axis (the… … -f-r-x Fig. 21.
