In this case, therefore, we shall obtain three paraboloid boundary curves, as shown in Fig. 93.
Behind this was a curious, paraboloid projector made up of hundreds of tiny, carefully orientated coils.
Also, the form of cambered surface should be a paraboloid—not arc or arc of circles.
If it lies at the infinity, the plane at infinity is a tangent plane, and the surface is called a paraboloid.
The Silky Epeira also has all the elbow-room she needs; and her paraboloid is not without elegance.
