complex numbersHELP!!! Last edited by cooljackiec (20130205 14:01:28) I see you have graph paper. You must be plotting something #2 20130205 14:47:31
Re: complex numbersYou can use binomial theorem,or you can use moivre's formula(i may have spelled incorrectly) #3 20130206 02:15:58
Re: complex numberswhenever i do binomial theorem, i keep getting the same thing, but its wrong I see you have graph paper. You must be plotting something #6 20130206 10:14:21
Re: complex numbersHi cooljackiec! Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional). LaTex is like painting on many strips of paper and then stacking them to see what picture they make. #7 20130206 11:56:16
Re: complex numbersI got 26, I don't remember how, but I used binomial theorem. It is wrong I believe I see you have graph paper. You must be plotting something #8 20130206 12:32:10
Re: complex numbersHi; put a = 1 separate the odd and even powers and plug in (√3)i for b. Even ones first, then odd. Add 64 + 0, answer is 64. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
