Expert Solution

Explanation of Solution

Given information:

  2xy|xy|x2+y2 .

Calculations:

Now here it is given,

  2xy|xy|x2+y2

Therefore it can be written as,

  2xyx2+y2x2+y22xyx2+y22xy0 (xy) 2 0

Therefore the interval can be written as,

  0|xy|2xy(xy)2

Using the values of the interval and using a graphing tool we draw the graph below.

The shaded region shows the values above zero in the interval.
