A complex number on a complex plane
This video shows that a complex number can be represented on a plane using it real and imaginary parts. Given a complex number, z=x+iy, the complex number z can be see as the point (x,y) on a plane.
We also discussed that a complex point can be located in a polar plane using the length of the line that connects the point (x,y) to the origin,(0,0) and the angle which the line makes with the real axis.
We are able to find that the length of the line is sqrt(x²+y²) and the angle is arctan(y÷x).
