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 coordinate.

You decide to first write a program that given a single 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.
