Copy of What is a complex number?
An alternate way to refer to complex numbers.
How can we transform a "normal" coordinate plane (the Cartesian plane) into the complex plane?
How do the values of a and b affect the position of a complex number (written as a+bi) on the plane?
When will a complex number (of the form a+bi) be a point on the real axis?
When will a complex number (of the form a+bi) be a point on the imaginary axis?
Change the coordinates of A to the same point in each grid. In the second grid, what does the number in black represent? How could you calculate that value from your point on the first grid?
