Thread: Word Subscript Mystery

Replied to a post by copying from a word document and the subscripting didn't carry over.

However, subscripting carried over to a new post, as shown below.

Now, out of curiousity, I will reply to this post by copying the same material from the Word document and see what happens.

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

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

(s₁₁²+s₂₂²+s₃₃²)² = 4[s₁₁²s₂₂²+s₁₁²s₃₃²+s₂₂²s₃₃² + 2(s₁₁+s₂₂+s₃₃)(s₁₁s₂₂s₃₃) and s_ii=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:

s_ii⁴ = s_ii²s_jj²

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.
