Is it possible to get a 4 digit pin from this?

Question

This is the problem to be solved

This just came across my social media feed and my first thought was "haha funny" but then I tried playing around with the equation and didn't see a way to get a 4 digit pin. Is it possible to pull a 4 digit pinout of this equation?

Answer 1

I would be happy if you show your step - by - step solution for me to help you in which parts that you not understand or cannot solve.

For conclusion, the final answer is : -2.981266944005536....
So, if first 4 digit, then the pin will be : 2981
So, if first 4 decimal digit, then the pin will be : 9812

Thank you.
