Yes and it is z=x+iy
That is often called the coefficient.
The answer depends on the context. It is often the variable used for the fourth dimension.
Time is often an independent variable.
In a formula, "B" typically represents a variable or parameter that is distinct and often used to denote a specific value, such as a constant or a specific quantity. In contrast, "b" usually denotes a different variable or a smaller value, which could represent a subset or an alternative measurement. The distinction between uppercase and lowercase letters often indicates different contexts or roles for these variables within the equation or formula.
How often the value of a random variable is at or below a certain value.
It can be though it is more often used to denote a variable.
An asterisk, not to be confused with Asterix who is a cartoon character, is used to denote multiplication (or times) ie a*b = a times b. Some old programming languages/computers used double asterisks to denote exponentiation ie a**b = ab. This was because x was often used to denote a variable and its use to denote multiplication could cause confusion.
In algebra, a variable is usually symbolized by the letter x. For more complex problems, the letters y and z are often used as well.
It is likely the symbol for the partial derivative, ∂, often used in mathematics to denote differentiation with respect to one variable while treating others as constants.
That is often called the coefficient.
To denote is an indication of something, such as a fever often denotes an infection.
That is called a variable. A letter is often used.
The answer depends on the context. It is often the variable used for the fourth dimension.
Characters that appear in front of variables are often; either a constant (any designated number) which is often called a coefficient, a different variable, or an operator such as an integrand or derivative.
The symbol commonly used to denote entropy is S.
A monomial with a coefficient if often called a term.
2x + 3 Or 5x7 + sqrt(3)*y4 The coefficients are often integers but can be irrational or even complex numbers. Polynomials are often concerned with one variable but there is no reason why that should be. Polynomials with n terms often consist of powers of the variable (x) up to n-1 but again, there is no reason to be bound by that.
