WebImaginary numbers, in the mathematical sense, were invented to complement the "real" numbers and are very useful in forming a complete number theory. I'll try to give some context. "Real" numbers are the numbers along the number line "from -infinity to +infinity" in non-technical terms. For example, -1, 0, 2.5, are real numbers. WebThe first serious and systematic treatment of complex numbers had to await the Italian mathematician Rafael Bombelli, particularly the first three volumes of his unfinished L’Algebra (1572). Nevertheless, the notion of a number whose square is a negative number left most mathematicians uncomfortable. WebWhen imaginary numbers were first discovered, it was not clear how they fit into the number system or how they could be represented on the Cartesian plane. This conundrum led to the ingenious invention of a diagram by Argand that made it possible to show the relation of imaginary numbers to real ones. first osage baptist church
