Argand diagram

An Argand diagram is a visual way to represent complex numbers, which have both a real part and an imaginary part. Imagine a coordinate plane: the horizontal axis shows the real component, and the vertical axis shows the imaginary component. Each complex number is plotted as a point or arrow based on its values. This helps us understand operations like addition, subtraction, and multiplication visually. It's a useful tool in fields like engineering and physics, making the behavior of complex numbers easier to grasp by translating abstract concepts into a clear graphical form.
