Thread: Word Subscript Mystery

Copied from Word the same as in first post.


Any explanations or suggestions?


(s112+s222+s332)2 = s114+s224+s334 + 2(s112s222+ s112s332+ s222s332)

(s11+s22+s33)2 = s112+s222+s332 + 2(s11s22+ s11s33+ s22s33) = 0 because sii=0. So
s112+s222+s332 = -2(s11s22+ s11s33+ s22s33)

(s112+s222+s332)2 = 4[s112s222+s112s332+s222s332 + 2(s11+s22+s33)(s11s22s33) and sii=0. So
s112s222+s112s332+s222s332 = ¼(s112+s222+s332)2 and substitute this into first eq to get:

s114+s224+s334 = ½(s112+s222+s332)2 , or in indicial notation:

sii4 = sii2sjj2

Tried copying from first post to this reply- didn't work.

Then tried copying from first post to a reply in another post, which worked before as a work-around but not this time. It looks like the work-around has been corrected.

I realize it's a bit ugly, but why not just use the LaTeX on the site? It sounds like the Word equation formatting simply doesn't agree with the site software.
