What does the c mathematical symbol mean?

The mathematical symbol c represents a complex set. It is often used as a symbolic expression of text description ellipsis in mathematical calculation and other occasions. It is often used as a symbolic expression of text description ellipsis in mathematical calculation and other occasions. Order. The value of the positive square root of the square sum of the real part and imaginary part of a complex number is called the module of the complex number, which can be recorded as | z |.

The meaning of mathematical symbols

Constant is a fixed value. For example, the ratio of the circumference to the diameter of a circle is π, and the expansion coefficient of iron is 0.0000 12. Constant is a name with a certain meaning, which is used to replace numbers or strings, and its value never changes. In mathematics, a capital c is often used to represent a constant.

Complex number is the conceptual extension of number. We call a number in the form of z = a+bi (both a and b are real numbers) a complex number, where a is called the real part, b is called the imaginary part, and I is called the imaginary part. The set of complex numbers is represented by C, and the set of real numbers is represented by R. Obviously, R is the proper subset of C, and the set of complex numbers is out of order, so the order of size cannot be established.
