Imaginary Numbers Can You Prove. But even though you already knew that fractions exist and didn t need this long argument proving it the point of going through the details of the argument is that exactly the same argument can be used to show that imaginary numbers exist. 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.
Can you take the square root of 1. In mathematics the symbol for 1 is i for imaginary. If i asked you to tell me the definition of the word mass you d tell me something like it s the property of matter that makes it heavy.

In our earlier discussion of imaginary numbers we learned how a picture of the complex number 2 3i can be drawn. 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. If we draw a right triangle in the picture then we have. But even though you already knew that fractions exist and didn t need this long argument proving it the point of going through the details of the argument is that exactly the same argument can be used to show that imaginary numbers exist.
