Imaginary Numbers And Complex Numbers. Re is the real axis, im is the imaginary axis, and i is the imaginary unit, that satisfies i 2 = −1. When we square an imaginary number, it gives a negative result.
4 rows a complex number is expressed in standard form when written a + bi where a is the real part and. Remember that the exponential form of a complex number is , where r represents the distance from the origin to the complex number and represents the angle of the complex number. A complex number is a combination of a.
