Examples of complex number
1) 3 + 4i
2) -2 + 5i
3) 1 - 2i
4) -1 - 3i
5) 2i
6) -5i
Sure! Here are a few examples of complex numbers:
1) 3 + 4i: This is a complex number in the form of a + bi, where a = 3 and b = 4. The real part of the number is 3, and the imaginary part is 4.
2) -2i: This is another complex number in the form of a + bi. In this case, a = 0 and b = -2. So, the real part is 0, and the imaginary part is -2.
3) 2 - i: Again, this is a complex number in the form of a + bi. Here, a = 2 and b = -1. Therefore, the real part is 2, and the imaginary part is -1.
4) 5: Although this appears to be a real number, it can also be considered a complex number with zero as the imaginary part. In this case, a = 5 and b = 0. Thus, it can be written as 5 + 0i.
These are just a few examples of complex numbers, which consist of a real part and an imaginary part. Complex numbers are used in various branches of mathematics, physics, and engineering to solve problems that involve both real and imaginary quantities.
