In each point, there is a line.
The curvature of the surface in this direction is zero.
Therefore the maximum curvature is positive and the minimum is negative.
Gauss curvature in this point is the product of this max and min, and therefore is negative (or zero).

Absolute monarchy is when a country is ruled by one person. There are pros and cons when is comes toabsolute monarchy. I think that absolute monarchy was positive for Europe during the 17thand 18thcentury.I think that absolute monarchy was positive because it was easy to understand.

1556 to something but he ruled Germany and Spain not sure about the Netherlands or England.
A cylinder has 2 flat surfaces and 1 curved surface.In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines. As such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinderrespectively; these have no flat surfaces.
A counting chamber is an accurately dimensioned chamber in a microslide which can hold a specific volume of fluid and which is usually ruled into units to facilitate the counting under the microscope of cells, bacteria, or other structures in the fluid.
