YES IT WAS POSTED BEFORE BUT SOME DUDE'S ANSWER (unfortunately wasnt helpful) WAS COUNTED AS AN ANSWER SO IT LOOKS LIKE MY QUESTION WAS ANSWERED

 

PLEASE DONT ANSWER UNLESS YOU HAVE THE EXPLENATION TO MY QUESTION. I KNOW HOW TO CALCULATE STUFF, I DO HAVE A CALCULATOR. PLEASE DONT ANSWER UNLESS YOU CAN EXPLAIN WHY AND WHERE IM WRONG

and now i can finally begin.... 

 

 

 

Please help.

https://en.wikipedia.org/wiki/De_Moivre%27s_formula

According to the formula (cos(60)+sin(60)*i)6=cos(360)+sin(360)*i=1+0*i=1

 

so cos(60)+sin(60)*i=1

or cos(60)+sin(60)*i=-1

 

so is cos(x)+sin(x)*i,

(works for every x)

 

but it doesnt make any sense..... (calculate it its wrong)

Okay I don't know how to do your question I'm not that far in math BUT I do know a little bit about this sight the question is not officially answered until a moderator or the admin looks at it and puts a check mark saying that the answer is correct or answers the question themselves. Also if the way that person explained it made no sence you should let that person know so that he/she can try to help  you understand.

Hmm.

 

1.Can i become a moderator?

2. i told him his answer didnt really help (politely of course) but i dont know how to reply so i just wrote it as an answer. im not surehe checked it because he was a guest

3. should i post it again? (Because your answer counts as an answer to my question)

Thank you very much for explaining everything to me
