Best ResponseYou've already chosen the best response.0Imaginary numbers result when you are taking the square root of any negative number: For an example, \[\sqrt{1}\] = i \[\sqrt{25} = 5i\] The 'i' is kind of like the negative sign

Best ResponseYou've already chosen the best response.0I can help you understand what imaginary numbers are. So,the base of imaginary numbers is actually laid upon some of the things like \[\huge \ i=\sqrt{1}\] The other thing is \[\huge\ \omega=\frac{ 1+i \sqrt{3} }{ 2 }\]

Best ResponseYou've already chosen the best response.0\[\sqrt{1}\] doesn't exist as a the REAL number you are asking for, because there's no number that you can square (because of the SQUARE root) and gives you 1

anonymous

Best ResponseYou've already chosen the best response.0you just need to know what a square root is

anonymous

Best ResponseYou've already chosen the best response.0i know what a square root is ofc

anonymous

Best ResponseYou've already chosen the best response.0that's why there's no sqrt of ANY negative numbers, because everthing squared is BIGGER than 0

Best ResponseYou've already chosen the best response.0so mathematicians around XVII century had to figure out another type of numbers, called COMPLEX numbers, and the first number of complex numbers is \[\sqrt{1}\]

Best ResponseYou've already chosen the best response.0that's why i said almost, because you figured out ANOTHER line, and that would make a 300 year old mathematician proud

anonymous

Best ResponseYou've already chosen the best response.0\(i\) is defined as the imaginary number such that \(i^2 = 1\), not \(i= \sqrt{1}\).

anonymous

Best ResponseYou've already chosen the best response.0and also its just common knowlige

ParthKohli

Best ResponseYou've already chosen the best response.0Yes, \(i\) is one of the square roots of \(1\). But \(i \ne \sqrt{1}\).

ParthKohli

Best ResponseYou've already chosen the best response.0I mean, \(\sqrt{1} =i,i\)

ParthKohli

Best ResponseYou've already chosen the best response.0So you must define \(i^2 = 1\) if you don't want things to mess up
