Quote: messed up in saying that 1/sqr(-1)=sqr(1/-1). the laws that made that true with real numbers don't apply with imaginary numbers. sqr(-1)=i. 1/i= i^(-1)=-i. also, the squareroot isn't a function, there are 2 different answers. sqr(-1)=i and sqr(-1)=-i. He basicly said that square roots can be negitive, but everyone kind of glossed over that... Actually, Majorgames86 noticed the flaw, but hes not very good at communicating.

Thus, it would equal √1, which simplifys to 1. In order to get the answer -1, it should be written like this: - √(-1)Ã‚Â² = -1 [quote=ReadMe] √(-1)Â² = -1 [/quote] In the case of √(-1)Â² = -1, the (-1)Â² is a quantity within a radical, it must be done before simplifying.

And glenn is correct above, but thats due to my notation not being very good in this text. look at it this way: ((-1)^0.5)^2 = (-1)^(0.5 x 2) = (-1)^1 = -1 jesus, you try have a decent intellectual discussion and everyone has a go at u - lets go back to spamming and pointless net shall we? And glenn is correct above, but thats due to my notation not being very good in this text. look at it this way: ((-1)^0.5)^2 = (-1)^(0.5 x 2) = (-1)^1 = -1 ________________ Cant be arsed to remake my sig.

Also, for anyone who for some reason doesn't believe me about the square root thing, here's some webpage that I found that talks about it. Quoted :: Some Webpage The product of two positive numbers and the product of the same two negative numbers is the same positive number. This means the square root can be written as a positive and/or negative number. Mathematicians use principal square root when they are discussing positive square roots and negative square root when they refer to negative square roots. If the radical sign, √, is used: √ = principal square root - √ = negative square root Well... that settles the manner . Well, doing it that way makes more sense for your purpose.
