Re: acute angle
Well, I didn’t find the solution the following way – but now that I’ve found the solution, it finally hit me that I could have done it the following way instead of the messy method I used.
The roots of the complex equation
The sum of the roots is equal to 0. QED.

Hi tony123,
The way you wanted:
