Equatives equate the referents of the two expressions on either side of the copular verb. Neither is a predicate of the other. Specificational clauses involve assigning a value to a variable: the subject expression sets up a variable and the post-copular expression provides the value for that variable.
The equative case is also found subdialectally in the Khalkha dialect of Mongolian, where it can be formed by adding the suffixes -цаа [tsaa], -цоо [tsoo], -цээ [tsee] or -цөө [tsöö], depending on the vowel harmony of the noun.
An example of this is: What the guests need for breakfast is an omelette. Here, the theme—the grammatical point of departure—is in bold text; it announces at the start to the listener or reader what the message will be about—the writer's or speaker's angle ("I'm going to tell you what they need for breakfast").
Common homework assignments may include required reading, a writing or typing project, mathematical exercises to be completed, information to be reviewed before a test, or other skills to be practiced. The effects of homework are debated. Generally speaking, homework does not improve academic performance among young children. Homework may ...
An example of the second case is the decidability of the first-order theory of the real numbers, a problem of pure mathematics that was proved true by Alfred Tarski, with an algorithm that is impossible to implement because of a computational complexity that is much too high. [122]
The definition of success in a given cloze test varies, depending on the broader goals behind the exercise. Assessment may depend on whether the exercise is objective (i.e. students are given a list of words to use in a cloze) or subjective (i.e. students are to fill in a cloze with words that would make a given sentence grammatically correct).
A numerical solution to the heat equation on a pump casing model using the finite element method.. Historically, applied mathematics consisted principally of applied analysis, most notably differential equations; approximation theory (broadly construed, to include representations, asymptotic methods, variational methods, and numerical analysis); and applied probability.
Smale's problems is a list of eighteen unsolved problems in mathematics proposed by Steve Smale in 1998 [1] and republished in 1999. [2] Smale composed this list in reply to a request from Vladimir Arnold, then vice-president of the International Mathematical Union, who asked several mathematicians to propose a list of problems for the 21st century.
