Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. Letters are used for representing many other types of mathematical object. As the number of these types has increased, the Greek alphabet and some Hebrew letters have also come to be used.
A closed curved stroke is a bowl in b d o p q D O P Q; B has two bowls. A bowl with a flat end as in D P is a lobe. [8] A trailing outstroke, as in j y J Q R is a tail. The inferior diagonal stroke in K is a leg. [9] The bottom of the two-story g is a loop; the very short stroke at the top is the ear. [10] The letters i j each have a dot or ...
In typography, the x-height, or corpus size, is the distance between the baseline and the mean line of lowercase letters in a typeface. Typically, this is the height of the letter x in the font (the source of the term), as well as the letters v , w , and z .
For example, the upper right branch of the curve y = 1/x can be defined parametrically as x = t, y = 1/t (where t > 0). First, x → ∞ as t → ∞ and the distance from the curve to the x-axis is 1/t which approaches 0 as t → ∞. Therefore, the x-axis is an asymptote of the curve.

Gaussian curve with a two-dimensional domain Many shapes have metaphorical names , i.e., their names are metaphors : these shapes are named after a most common object that has it. For example, "U-shape" is a shape that resembles the letter U , a bell-shaped curve has the shape of the vertical cross section of a bell , etc.
The values of u, v, w such that g(u, v, w) = 0 are the homogeneous coordinates of the points of the completion of the curve in the projective plane and the points of the initial curve are those such that w is not zero. An example is the Fermat curve u n + v n = w n, which has an affine form x n + y n = 1. A similar process of homogenization may ...
