Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
A proof in infinitary logic from a theory is a (possibly infinite) sequence of statements that obeys the following conditions: Each statement is either a logical axiom, an element of , or is deduced from previous statements using a rule of inference. As before, all rules of inference in finitary logic can be used, together with an additional one:

In mathematics, limit cardinals are certain cardinal numbers. A cardinal number λ is a weak limit cardinal if λ is neither a successor cardinal nor zero. This means that one cannot "reach" λ from another cardinal by repeated successor operations. These cardinals are sometimes called simply "limit cardinals" when the context is clear.
() (using x ≥ 0 to obtain the final inequality) so that: = One must use lim sup because it is not known if t n converges. For the other inequality, by the above expression for t n , if 2 ≤ m ≤ n , we have: 1 + x + x 2 2 !
In multivariable calculus, an iterated limit is a limit of a sequence or a limit of a function in the form , = (,), (,) = ((,)),or other similar forms. An iterated limit is only defined for an expression whose value depends on at least two variables. To evaluate such a limit, one takes the limiting process as one of the two variables approaches some number, getting an expression whose value ...
The Greek letters of the society's name were selected to represent Alpha for First, Sigma for Scholarship, and Lambda for Leadership. [3] The motto of Alpha Sigma Lambda is "First in Scholarship and Leadership". [3] The society's crest displays the Greek letters ΑΣΛ and its symbols, the book, the lamp, and the torch. [1]
Kappa Lambda Chi was founded on July 4, 2013, in Clinton, North Carolina, as an alternative to traditional Greek letter organizations for male service members. [1] [2] [3] Its founding members were Sir Zachary D. S. Wyatt II (Air Force veteran), William C. Dickey (Army retired), and James K. Jackson (Army retired).
