To understand this equation geometrically, think of the complex plane where
. The equation
represents all points that are a distance of 2 units from the point
on the complex plane. This means you are looking at a circle centered at
with a radius of 2. So, simply put, any point on this circle satisfies the equation!
To solve for
, we can express
. Plugging this into the modulus equation gives us
. Squaring both sides leads to
. Now you can see that you’ve derived the equation of the circle! Just solve the equation further to find specific points on this circle.
