Complex numbers and complex questions!
Whats square root of -1? Even if u had basic maths in school , you will realise that its i(defined as square root of negative). Big deal..I have been dealin with this for almost half of my life (being an electrical engineer..i is impossible to escape) But then sometimes I think its fine..but what does i mean in "reality". There are thousands of definations... i is the part of y axis of argand diagram...i means an operation of 90 degree rotation..etc etc.. but just think about this.. i= sqrt(-1) lets define all this in "reality" 1= as in one ness..one apple , two apple..etc sqrt= operation defining a number multiplied by the same (inverse) - = subtract(take away) now what does i represent? where is i in the "real world"? 1 is there, sqrt is there, subtract is there....but where the f$%% is i? first of all is "i" allowed in real numbers? what is it ? I think i know the answer..or maybe its a guess.. There is no "i" in the real wor...
