A common visualisation of complex numbers is the use of Argand Diagrams. To construct this, picture a Cartesian grid with the x-axis being real numbers and the y-axis being imaginary numbers. In some branches of engineering, it’s inevitable that you’re going to end up working with complex numbers. Fortunately, though, you don’t have to run to another piece of software to perform calculations with these numbers.

The formula is still valid if x is a complex number, and so some authors refer to  The Euler formula, sometimes also called the Euler identity (e.g., Trott 2004, p. 174), states. e^(ix)=cosx+isinx,. (1).

3 Euler’s Identity stems naturally from interactions of complex numbers which are numbers composed of two pieces: a real number and an imaginary number; an example is 4+3 i. The Imaginary Number At some point in your life, you've probably encountered the imaginary number, i. In case you haven't, i is defined as the square root of -1. In other words, it's a number so An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. By definition, zero is considered to be both real and imaginary.

The imaginary number i: i p 1 i2 = 1: (1) Every imaginary number is expressed as a real-valued multiple of i: p 9 = p 9 p 1 = p 9i= 3i: A complex number: z= a+ bi; (2) where a;bare real, is the sum of a real and an imaginary number. The real part of z: Refzg= ais a real number. The imaginary part of z: Imfzg= bis a also a real number.
