May 16, 200917 yr ^ can't take the root of a negative number because there is no number which, multiplied by itself, gives a negative. He never took the square root though. In conventional mathematics without complex numbers, you can't even write down -1^0.5 Doesn't it just work out to be -1 though? -1^0,5 =/= -1 It's i. My blog
May 16, 200917 yr Yeah okay, I'll take your word for it. Honestly, things get complicated as soon as someone introduces the concept of infinity. Denizen of Darkness| PSN= sworddude198

May 16, 200917 yr (1^(1/2)/-1^(1/2)) = (-1^(1/2)/1^(1/2)) 1/i =- i/1 1/i = -i As 1^0.5 x -1^0.5 = i,both sides times i. 1 = 1. I was about to show the exact same thing but without the complex numbers. Your way works just the same though : :

May 16, 200917 yr ^ can't take the root of a negative number because there is no number which, multiplied by itself, gives a negative. incorrect, use of the integer I or J in physics allows the root of a negative number. the actual mistake is the belief that the root of an entire fraction is the same as the root of the nominator and denominator, this is infact FALSE fo all all numbers belonging to the set of real numbers. Look guys... I absolutely must be a mass baby-seal murderer!

May 16, 200917 yr Author (1^(1/2)/-1^(1/2)) = (-1^(1/2)/1^(1/2)) 1/i =- i/1 1/i = -i As 1^0.5 x -1^0.5 = i,both sides times i. 1 = 1. I was about to show the exact same thing but without the complex numbers. Your way works just the same though : : Or the fast way... -1=-1 -1(-1)=-1(-1) 1=1 I know you are just disproving someone else's equation, I just really had the urge to post that. I shall take my flock underneath my own wing, and kick them right the [bleep] out of the tree. If they were meant to fly, they won't break their necks on the concrete.So, what is 1.111... equal to?10/9. Please don't continue.

May 17, 200917 yr I don't have a mind for maths, unfortunately. Whenever I think of a mathematical problem I do best to keep it simple and, if possible, think of each unit as a physical object. For example, I rationalise dividing by zero to be nonsensical because you can't divide a number of objects into zero groups. They'll always be in groups, even if it's just groups of one. Then you might have a mind for physics, where every number has set significance and you are not left in a void of variables and symbols with no meaning. Perhaps. I think that I have a mind for molecular biology more than anything else. It's all easily understandable on a physical level. It's too late to seriously consider any other field of science anyway.
May 22, 200917 yr infinity x 0 x 2 = 1 infinity x 0 = 0 0 x 2 = 0 (not 1) Whats next. Are you goign to discard the fabric of life by proving; 1+1 does not = 2? Or that the trig functions are incorrect? Or you can magically apply pytharogas's theoreom to a equilateral triangles... (Yes it is possible, I realise that...) EDIT: Yeah, I just read the first post ;-; I failed epically. But yeah, people have been applying wrong algebraic equations, etc... (silly people) Luck be a Lady
May 23, 200917 yr If you can find the error here I'll be bloody impressed :P -1 = -1 (1/-1) = (-1/1) (1^(1/2)/-1^(1/2)) = (-1^(1/2)/1^(1/2)) multpily by 1^(1/2).-1^(1/2) and you get 1= -1 Q.E.D PLAWKS? (1^(1/2)/-1^(1/2)) = (-1^(1/2)/1^(1/2)) 1/i =- i/1 1/i = -i As 1^0.5 x -1^0.5 = i,both sides times i. 1 = 1. I was about to show the exact same thing but without the complex numbers. Your way works just the same though : : the rule sqrt(a) * sqrt(B) = sqrt(ab) only applies for real numbers, and sqrt(-1) isn't a real number.
