What does the C symbol mean in math?
“C” indicates a set of Complex numbers. The symbol “C” over the integral sign means close integral. In set theory “C” (“U” rotated clockwise by 90) means “Subset of”. In the standard equation of a straight line. y = mx + c, the constant m denotes slope if the line & “c” denotes interest of the line on Y-axis.
What is not an element of symbol?
∉
| Symbol | Meaning | Example |
|---|---|---|
| a ∈ A | Element of: a is in A | 3 ∈ {1, 2, 3, 4} |
| b ∉ A | Not element of: b is not in A | 6 ∉ {1, 2, 3, 4} |
| Ø | Empty set = {} | {1, 2} ∩ {3, 4} = Ø |
| Universal Set: set of all possible values (in the area of interest) |
Is CA proper subset of A?
A proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B. The set C={1,3,5} is a subset of A, but it is not a proper subset of A since C=A.
Does A or B include A and B?
In mathematical contexts, you would say “between two numbers a and b, inclusive…” thus implying that a and b are included. It’s not as common to see the complementary “between a and b, exclusive” though, which would indicate a and b are not included.
