Step 1
The given expression is 4i.
The Cartesian point in complex plane is (0,4).
The graph is shown below:

Step 2
The distance formula for points on the Cartesian plane:d=(x2x1)2+(y2y1)2.
d=(00)2+(04)2
=0+16
=4
The absolute value of the number 4i is 4.

Find an open set V containing ( 1 , 1 ) such that f | V : V f ( V ) is bijective, where f : R 2 R 2 & f ( x , y ) = ( x y , x y )
My Question: Clearly f ( x 1 , y 1 ) = f ( x 2 , y 2 ) x 1 y 1 = x 2 y 2 & x 1 y 1 = x 2 y 2 , thus x 1 2 + y 1 2 = x 2 2 + y 2 2 . Hence both ( x 1 , y 1 ) and ( x 2 , y 2 ) are points of intersection of the same line and circle. But Then how do I find the open set V?
