As we have already discussed, in mathematics set theory, a set is a collection of different types of objects, and collectively it is called an object. For example, numbers 8, 10, 15 and 24 are 4 distinct numbers, but when we put them together, they form a set of 4 elements, such that {8, 10, 15, 24}. Sorted by: 90. It is borrowed from computer programming: it means that the item on the left hand side is being defined to be what is on the right hand side. For example, y:= 7x + 2 y := 7 x + 2. means that y y is defined to be 7x + 2 7 x + 2. This is different from, say, writing. 1 =sin2(θ) +cos2(θ) 1 = sin 2 ( θ) + cos 2 ( θ)Real numbers lie on the horizontal axis, and imaginary numbers lie on the vertical axis. The imaginary unit or unit imaginary number ( i) is a solution to the quadratic equation . Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication.

Vectors have both size (magnitude) and direction. The numbers xj are called the components of →x. Using this notation, we may use →p to denote the position vector of point P. Notice that in this context, →p = → 0P. According to a widely accepted theory, the letter N stands for sample size, and the word N generally refers to population size. N, on the other hand, is perceived by some as the total sample size and N, as a portion of the sample.

Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A".Sign of a number.

N (0,1) is the most common normal distribution used. If the mean is higher, than the distribution shifts to the right (left if lower). If the variance is higher then the distribution is wider and flatter (thinner and taller if lower).In combinatorics, the “n!” symbol is used to calculate the number of possible arrangements of a set of items.
