This set includes numbers like 3− 2i and 1 + 6i. Any real number can be expressed in complex form, as can every purely imaginary number. For instance, the real number 5 can be written in complex form as 5 + 0i where the imaginary part is 0.
WitrynaThink of the complex number as a 2-dimensional vector in a plane. Addition of two complex numbers looks exactly like vector addition, either graphically or algebraically (as in the addition example above and in Figure 2). And z r x2 y2 is just the length of the vector. Looking at Figure 1, you can see that I I sin cos y r x r WitrynaAlso, ib is called an imaginary number. Some of the examples of complex numbers are \(2+3i, -2-5i, \,\,\dfrac 1 2 + i\dfrac 3 2\), etc. Power of i. The alphabet i is referred to as the iota and is helpful to represent the imaginary part of the complex number. Further the iota(i) is very helpful to find the square root of negative numbers.
