Imaginary Numbers For Dummies. Now rather than focusing on imaginary numbers i i i2 i 2 look at the general pattern. 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 i 2 1.
In the complex number a bi a is called the real part and b is called. The imaginary unit denoted i is the solution to the equation i 2 1. We were talking about number systems when i mentioned the imaginary numbers and she burst into laughter.
Displaystyle i the key concept to note here is that none of these purely imaginary numbers lie on the real number line.
An imaginary number is basically the square root of a negative number. It exists on the real number line. Unit imaginary number the square root of minus one 1 is the unit imaginary number the equivalent of 1 for real numbers. Or anything with a cyclic circular relationship have anything in mind.
