A set X is called a proper subset of a set Y if X is contained in Y but not equal to Y.
they are called quadrant 1st quadrant lies between x,y 2nd quadrant -x,y 3rd quadrant -x, -y 4th quadrant x, -y
The genes carried on the X and Y chromosomes are called your "sex chromosomes".
No, the origin is the point where the x-axis and y-axis meet in the coordinate plane. The x value of an ordered pair is called the abscissa (the y value is called the ordinate).
All chromosomes that are not either X or Y are called autosomes.
A natural number is y is called perfect square if there exists an integer x such that y=x2
Yes. That property is called anticommutative.
because they are normally the unknown variables
(x^1, y^1) + (x^2, y^2)
An identity is a statement which says two quantities are equal, like as x + y = y + x or sin (x + y ) = sin x cos y + cos x sin y .
The sex chromosomes do. They are called X and Y. Females have two X's and males have an X and a Y.
It is called the independent variable. For example if you are trying to find y: y = x+1 X is the independent variable, and Y is the dependent variable. The value of Y, depends on the value of X.
