An integer can be denotated by any letter. Teachers/professors may use different letters as a means to represent on a graph (i.e. x,y,z axis), but there is usually no real meaning behind why the letter 'z' was chosen over 'q'.
why an set of integer denoted by z
Set of integers is denoted by Z, because it represents the German word Zahlen which means integers
It is Z from the German for "to count". The counting, or natural numbers are denoted by N.
There are no real reason why it is denoted by z, but that the real number axis is denoted by x, imaginary number is denoted by y, the real part of a complex number is denoted by a, the imaginary part of a complex number is denoted by b, so there is z left.
No, 1/2 is not an integer. Integers are the natural numbers (1,2,3,4,...) together with their negatives and zero. Then integers (Z) can be denoted as Z = {...,-3,-2,-1,0,1,2,3,...}.1 over 2 (1/2) is not an integer. Integers are numbers like 1,2,3,4, and -17. Integers do not include fractions.
Symbol Z comes from the German word Zahl 'number',
Z is from Zahl (number in the German language).
Symbol Z comes from the German word Zahl 'number',
Integer ambiguity refers to the initial epoch of a continuous tracking in the carrier phase measurement, usually it is denoted as N.
