Re: ?????

I think this is the thread you're looking for smile

Check #9 for matrices.

Re: ?????

Well, that thread should tell you; perhaps you simply made an error.

If you want further reading on LaTeX or to clear up how to program matrices then go to this excellent website (which is a must for your 'favorites'):
http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/

EDIT: 'Matrices and arrays' shouldn't be far down the page wink

Re: ?????

Re: ?????

Start off with the definition of a determent, then simply plug and chug.

Re: ?????

Are you sure its not this:

because when im trying to solve it im getting negative of the expression

i don't like playing with alpha, beta and gammas so im using
alpha = x   beta = y      gamma = z
Here it is:
you take the right hand side(RHS) of the expression and then expand it

RHS= (y-x)(z-x)(y-z)
      = (yz-yx-xz+x²)(y-z)
      = y²z-xy²-xyz+x²y-yz²+xyz+xz²-x²z
(now rearrange them and combine like terms)
      = y²z-yz²+xz²-x²z-xy²+x²y
      = -1(-y²z+yz²-xz²+x²z+xy²-x²y)
      = -1[(yz²-y²z)-(xz²-x²z)+(xy²-x²y)]
      =

   = -LHS (Left Hand Side of the equality)



this is what im getting...so check your question again
