Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions , such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing .
In the Euclidean plane, two circles that are concentric necessarily have different radii from each other. [3] However, circles in three-dimensional space may be concentric, and have the same radius as each other, but nevertheless be different circles.
In mathematics, the eccentricity of a conic section is a non-negative real number that uniquely characterizes its shape. One can think of the eccentricity as a measure of how much a conic section deviates from being circular. In particular: The eccentricity of a circle is 0. The eccentricity of an ellipse which is not a circle is between 0 and 1.
Algebraic geometry is a branch of mathematics which uses abstract algebraic techniques, mainly from commutative algebra, to solve geometrical problems.Classically, it studies zeros of multivariate polynomials; the modern approach generalizes this in a few different aspects.
