A complex number is a couple of two real numbers (x, y). We can think about complex numbers like points on the coordinate plane. x is the real part of z, and y is  30 Jan 2014 Complex numbers are numbers that consist of two parts — a real number and an imaginary number.

In spite of this it turns out to be very useful to assume that there is a number ifor which one has (1) i2 = −1. Having introduced a complex number, the ways in which they can be combined, i.e. addition, multiplication, division etc., need to be defined. This is termed the algebra of complex numbers. You will see that, in general, you proceed as in real numbers, but using i 2 =−1 where appropriate. But first equality of complex numbers must be defined.

Calculate the sum of these two numbers. ABS CN Calculate the absolute value of complex number -15-29i. Every complex number can be expressed as a point in the complex plane as it is expressed in the form a+bi where a and b are real numbers. a described the real portion of the number and b describes the complex portion.

Calculate the sum of these two numbers. ABS CN Calculate the absolute value of complex number -15-29i. Every complex number can be expressed as a point in the complex plane as it is expressed in the form a+bi where a and b are real numbers. a described the real portion of the number and b describes the complex portion. By using the x axis as the real number line and the y axis as the imaginary number line you can plot the value as you would (x,y) 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.
