Complex graphs

In one of the math assignments your teacher asks you to plot the following function:

Knowing the software available online, you do it very quickly. Yet, your teacher asks you to write your own program that would print this graph.

For that, as a first step, you would need to know the value of the function at each possible (x,y) coordinate.

You decide to first write a program that given a single (x,y)coordinate, would print the value of the function.

The input consists of two floating-point numbers x and y.

The program should print the value of the function written above.
