Caspar Wessel, a Norwegian and Danish mathematician was the first to porpose representing complex numbers in a two dimensional plane using real and imaginary axes. The idea was developed by Jean-Robert Argand, a Frenchman.
Certain functions, when solving to find the zeros (value which makes the function equal zero), the only value which will work has an imaginary component. Note that a parabola (graph of a quadratic or 2nd order polynomial) can touch the x-axis at a single point, or 2 points or no points. If it does not touch or cross the x-axis, then the root (or zeros) of the function are complex with imaginary components.Technically, all real numbers are a subset of complex numbers, so all numbers are complex - but this is not how we normally refer to them. We usually say that a number is real, or it is imaginary, or it is complex.

Euclid's Elements covered different topics that included plane geometry, solid geometry, and theory of numbers. This mathematical work consisted of thirteen books. Euclid lived between 325 and 270 B.C. and is regarded as the founder of geometry.
The advances that Chaldeans made were calendars and solving complex problems of geometry
An organ.
Analytic geometry.
No.
3 and 5 are both complex numbers, and if you multiply them together, you get 15, which is a real number. If you were looking for two non-real complex numbers, then any pair of complex conjugates will work. For example, 5+2i times 5-2i is 29.
Aristotle considered geometry one of the most important sciences, and did some work with point and line planar geometry. He also used geometry as a way into sciences where he did more work, like optics and mechanics.
The 16th century Italian mathematician, Gerolamo Cardano was the first to use imaginary and complex numbers in his work on cubic equations.
It is important to ensure that no one ignorant of geometry enters because geometry is a fundamental branch of mathematics that is essential for understanding and solving complex problems in various fields such as engineering, architecture, and physics. Without a basic understanding of geometry, individuals may struggle to comprehend and apply important concepts, leading to errors and inefficiencies in their work.
Because he contributed most to geometry. His work can be found in the Elements. It is divided into 13 books. Books 1-6 dealing with plane geometry. Books 7-8 about number theory. Book 9 on irrational numbers. While books 10-13 about three-dimensional geometry. answered by-G.L.R.-
