this tutorial just helped me solve a question that needed a similar approach

[@lanomusambazi8654]

And same with me you can imagine. I have struggled to know this part since 2019 only to know it today after two years of struggle. Thank you very much sir for the great knowledge you have imparted in me. This was actually the only remaining part I didn't know in complex numbers. Trigonometric identities using de moivres theorem. Wow I'm now walking with my head high.
