Z is the symbol for the set of integers. n E Z means n is an element of the set of integers, ie n is an integer. If pi/6 and -pi/6 are solutions, then so is every angle coterminal with pi/6 and -pi/6 (unless you are told to restrict your domain) Adding n2pi, ie an integer number of 2pi (full circles) accounts for all the coterminal angles.Mean.

Z = # of protons of an atom. A is used to signify the atomic mass number (also known as atomic mass or atomic weight) of an atom. A = # protons + # neutrons. A and Z are integer values. When the actual mass of an atom is expressed in amu ( atomic mass units) or g/mol then the ...As we have already seen in the first section, the cardinality of a finite set is just the number of elements in it. But the cardinality of a countable infinite set (by its definition mentioned above) is n(N) and we use a letter from the Hebrew language called "aleph null" which is denoted by ℵ 0 (it is used to represent the smallest infinite number) to denote n(N). i.e., if A is a countable ...It is called a quantifier. It means "there exists". When used in an expression such as. ∃x s.t. x > 0. It means "There exists a number x such that x is greater than 0." Its counterpart is ∀, which means "for all". It's used like this: ∀x, x > 0. Which means "For any number x, it is greater than 0."Section 3.1 : The Definition of the Derivative.

Also, an example is provided to understand the usage of mathematical symbols. x ≤ y, means, y = x or y > x, but not vice-versa. a ≥ b, means, a = b or a > b, but vice-versa does not hold true. . In a wide sense, as argued below, the answer is no. Indeed, R(z) ℜ ( z) is not a holomorphic function since its image is the real line. In this sense, there is no formula for R(z) ℜ ( z) that does not involve z¯ z ¯, because the Cauchy–Riemann equations fail for R(z) ℜ ( z) : This was said already in the comments.
