___ is any function which can be defined by a rational fraction, an algebraic fraction such that both the numerator and the denominator are polynomials. 相关知识点: 试题来源: 解析 Hence, it is a partial fraction. Partial fraction is any function which can be defined by a rational fraction,...
We prove that given two disjoint compact sets K 1 and K 2 in the complex plane, without any holes in them, there exists a sequence p n ( z ) of rational functions, all of them satisfying one and the same algebraic differential equation, such that p n ( z ) converges uniformly to ...
What are rational expressions? Why must we always be mindful of the final value of the denominator in a rational expression? For example, consider the rational expression 3x/(x2-16) . What values in the denominator must we be mindful of? Explain why. Find all excluded...
Determine the corresponding mathematical symbols for the given algebraic expressions in words. How to solve this problem using grouping symbols? 4^2 -5 \times 2+1=1 In these examples, why wouldn't we solve what's in both parentheses, and not just the top? Which...
Let Q be the set of all algebraic expressions of the form q= II aq(a) aEA for rational numbers q(a). Note that M is the subset of Q for which each q(a) is either zero or one. Note that Q has a countable number of elements. Without loss of generality, then, we can assume ...

Let α , γ be arbitrary algebraic numbers of degrees p − 1 and p, respectively. Then, it follows easily that the extension Q ( α , γ ) over Q has degree ( p − 1 ) p . Therefore, for all but finitely many rational numbers r we have Q ( α , γ ) = Q ( α ( r...
