The symbols of advanced mathematics include the following aspects:
1. Basic operation symbols: including plus sign (+), minus sign (-), multiplication sign (×), division sign (), etc. These symbols are used to represent basic mathematical operations.
2. Exponential symbols: including superscript () and subscript (_). Superscript is used to represent power operation, for example, A 3 represents the cube of a; Subscripts are used to represent exponents or powers, for example, a_i represents the i-th element a.
3. Root number: including square root number (√) and cubic root number (√). The square root symbol is used to represent the square root of a number, for example, √x represents the square root of x; The cube root symbol is used to represent the cube root of a number, for example, X (1/3) represents the cube root of X.
4. Absolute value symbol: including vertical line (|). Vertical lines are used to represent the absolute value of a number, such as |x| for the absolute value of X.
5. Trigonometric function symbols: including sine symbol (sin), cosine symbol (cos), tangent symbol (tan), etc. These symbols are used to represent the relationship of trigonometric functions, for example, sinx represents the sine value of X.
6. Calculus symbols: including integral symbols (∩), limit symbols (lim) and derivative symbols (d/dx). These symbols are used to represent the concepts and operations of calculus, such as ∫f(x)dx used to integrate the function f(x).
7. Matrix symbols: including capital letters A, B, C, etc. These letters are used to represent matrices. For example, A represents an m×n matrix.
8. Symbol set: including capital letters U, N, R, etc. These letters are used to represent sets, such as U for complete set, N for natural number set, and R for real number set.
