You can have up to 11 players on the field but most of the time you have 9.   There is the pitcher,catcher,third basemen,short stop,second basemen,first basemen,left â¦ field,center field,and right field.   The way you get up to 11 players is if you put some in right center and left center field.
A tuple is a fixed fixed-length list containing elements that need not have the same type. It can be, and often is, used as a key-value pair. A row (sometimes called a record) is the set of fields within a table that are relevant to a specific entity.
In the mathematical theory of singularities a cusp is a type of singular point of a curve. Cusps are local singularities in that they are not formed by self intersection points of the curve.The plane curve cusps are all diffeomorphic to one of the following forms: x 2 â y = 0, where k â¥ 1 is an integer. An ordinary cusp is given by x 2 â y 3 = 0, i.e. the zero-level-set of a type A 2 -singularity. 2  Let f (x, y) be a smooth function of x and y and assume, for simplicity, that f (0,0) = 0. 3  Then a type A 2 -singularity of f at (0,0) can be characterised by:
