It is used in engineering, physics, mathematics, astrophysics, and many other fields. It provides powerful tools for doing mathematical analysis, and often yields pleasing and unanticipated answers.
What is complex variable math?
complex variable, In mathematics, a variable that can take on the value of a complex number. In basic algebra, the variables x and y generally stand for values of real numbers. The algebra of complex numbers (complex analysis) uses the complex variable z to represent a number of the form a + bi.
What are the 3 types of variables in math?
In an algebraic equation, an independent variable describes a variable whose values are independent of changes.
Independent Variables
- Random variables.
- Categorical and continuous variables.
- Intervening variables.
- Moderator variables.
- Control variables.
- Extraneous variables.
- Free variables.
- Bound variables.
Who invented complex variable?
According to [9], “Cardano was the first to introduce complex numbers a + √−b into algebra, but had misgivings about it.” In Chapter 37 of Ars Magna the following problem is posed: “To divide 10 in two parts, the product of which is 40”.

What does complex in math mean?
Complex Numbers in Maths. Complex numbers are the numbers that are expressed in the form of a+ib where, a,b are real numbers and ‘i’ is an imaginary number called “iota”. The value of i = (√-1). For example, 2+3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im).
What is a complex function in math?
A complex function is a function from complex numbers to complex numbers. In other words, it is a function that has a subset of the complex numbers as a domain and the complex numbers as a codomain. Complex functions are generally supposed to have a domain that contains a nonempty open subset of the complex plane.
What is an example of a complex equation?
Complex Equations
Mathematically, i2=−1 i 2 = − 1 , and, as an example, the imaginary number 3i , when squared, equals -9.
What is a complex solution in math?
The discriminant, b 2 − 4 a c , indicates the types of solutions of a quadratic equation. If the discriminant equals 0, then the equation has one real solution, a double root. If the discriminant is less than 0, then the equation has two complex solutions.

It’s been named the Boolean Pythagorean Triples problem, and was first posed by California-based mathematician Ronald Graham back in the 1980s. The problem centres around the Pythagorean formula a2 + b2 = c2, where a and b are the shorter sides of a triangle, and c is the hypotenuse, or longest side.
