What does z stand for in math.

But to answer your question, root(f(z),z) stands for the set of values, z, such that f(z) == 0 -- the roots of f(z). The root() form can be used to express roots of polynomials even with degree higher than 4 (the maximum that is certain to have explicit roots.) .A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. Example: speed and travel time. Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written:MATLAB does that automatically in this case. But to answer your question, root (f (z),z) stands for the set of values, z, such that f (z) == 0 -- the roots of f (z).

5. Hilbert's epsilon-calculus used the letter ε ε to denote a value satisfying a predicate. If ϕ(x) ϕ ( x) is any property, then εx. ϕ(x) ε x. ϕ ( x) is a term t t such that ϕ(t) ϕ ( t) is true, if such t t exists. One can define the usual existential and universal quantifiers ∃ ∃ and ∀ ∀ in terms of the ε ε quantifier:In calculus and analysis, constants and variables are often reserved for key mathematical numbers and arbitrarily small quantities. The following table documents some of the most notable symbols in these categories — along with each symbol's example and meaning. π. If f ( x) → L, then f ( x) 2 → L 2.The Z score, also known as the "standard score", is the number of standard deviations away from the mean you particular observation is. For example, if the mean is 10, with a standard deviation of 2, and the observation is 14, the z score is 2, since you are 2 standard deviations above the mean. It works the same way below the mean.This page is a glossary of some of the more common symbols in mathematics, including what they mean and where they are used.MATLAB does that automatically in this case.
