# What are the applications of complex numbers in civil engineering and building?

I am not aware of any such application, except in electrical circuits.

### What are the applications of complex numbers?

There are numerous applications; you should read the Wikipedia article on complex numbers for more examples. Some applications include: Get a better understanding of math. Even if you do calculations with real numbers, working with complex numbers often gives a greater understanding. Electricity, with AC, uses complex quantitites. Quantum physics Art - ever seen the Mandelbrot set, or other fractals? There are numerous applications; you should read the Wikipedia article on complex numbers for more…

### What are imaginary numbers and how are they used in real life situations?

Imaginary numbers are a mathematical concept, first defined to handle the square root of negative numbers. At first, many mathematicians did not think very kindly of them, until Euler's formula in the 1700's, then later applications in electricity and wave analysis were recognized. Complex numbers are numbers on a plane, for which special which special operations are defined. Complex numbers have a real part, and an imaginary part. There are several practical applications; for example…

### Why do we use complex numbers?

Complex numbers are theoretically interesting; they help us better understand the real numbers in some cases.They also have some very practical applications, including: * Electrical circuits - in AC, things like resistance, current, and voltage acquire a phase angle, thus becoming complex numbers. * Quantum mechanics - the probability amplitude is described with a complex number. As a result, complex numbers basically permeate all of quantum mechanics.

### Applications of complex numbers and complex variables in engineering?

Complex equations and their graphs are used to visualize electrical and fluid flow in the real world. For instance, the equation z+1/z can show the flow of water around a circular piling. The equation (z-1)/(z+1) and the graph can show the electrical force fields around two parallel wires carrying current.

### Jobs that require the use of imaginary numbers?

Physics (e.g., quantum mechanics, relativity, other subfields) makes use of imaginary numbers. "Complex analysis" (i.e., calculus that includes imaginary numbers) can also be used to evaluate difficult integrals and to perform other mathematical tricks. Engineering, especially Electrical Engineering makes use of complex and imaginary numbers to simplify analysis of some circuits and waveforms.

### In which other fields is the lettr you of imaginary number used?

Imaginary, or more precisely complex numbers (vectors that have a real part and an imaginary part) are used in a variety of fields, including: Electrical engineering - in AC, several quantities are best described by complex numbers. Quantum physics Theoretical math - often, an understanding of complex numbers can even help you better understand real numbers. Art - for a start, take a look at the Mandelbrot Set! And many others more.

### Why are imaginary numbers important?

They are used for working out equations where the numbers you are working with are not physically possible, but we just imagine they are, such as the square root of a negative number In engineering, especially Electrical Engineering, using complex numbers to represent signals (rather than sines and/or cosines) make comparing and working with signals easier.

### What is the difference between a complex number and a non real complex number?

Think of the complex numbers as points on a coordinate system. Instead of the usual x-axis you have the real numbers, instead of the y-axis, you have the imaginary numbers. The real numbers are on the horizontal axis. The imaginary numbers are on the vertical axis. The complex numbers are any number on the plane. The non-real complex are, of course, any complex numbers that are not on the real number axis - not on…

### The sum of two complex numbers is always a complex number?

A "complex number" is a number of the form a+bi, where a and b are both real numbers and i is the principal square root of -1. Since b can be equal to 0, you see that the real numbers are a subset of the complex numbers. Similarly, since a can be zero, the imaginary numbers are a subset of the complex numbers. So let's take two complex numbers: a+bi and c+di (where a, b…

### What are complex calculations?

This probably refers to how to handle computations with the set of Complex Numbers (which is a combination of the set of real numbers and imaginary numbers), rather than just complicated calculations, or calculations which are very involved and as-such appear very complex (which is a different thing than Complex Numbers).

### What is a complex set?

The set of complex numbers is the set of numbers which can be described by a + bi, where a and b are real numbers, and i is the imaginary unit sqrt(-1). Since a and b can be any real number (including zero), the set of real numbers is a subset of the set of complex numbers. Also the set of pure imaginary numbers is a subset of complex number set.
