Subject: MathML to LaTeX producing extremely lossy output, especially with quotients
Date: Tue, 1 Nov 2016 13:38:00 -0700 (PDT)	[thread overview]
Message-ID: <48401935-a82d-44e6-afa5-810c580f9edf@googlegroups.com> (raw)


[-- Attachment #1.1: Type: text/plain, Size: 11678 bytes --]

I am attempting to translate some MathML snipped from .docx files in 
Microsoft Word to LaTeX in order to make accessible materials for some 
visually impaired students. I was hoping to do it this way so that we could 
provide them with both a screen-readable HTML file AND a Nemeth Braille 
Transcription so as to give them multiple forms of presentation to avoid 
any issues with inaccurate translation or our mistakes.

I'm going to give up on this route and try something else, maybe trying to 
translate the whole docx file directly, or copying the MathType output 
straight to LaTeX.

Powers of X Rule\\
if f( x )= x n then f ′ ( x )=n ( x ) n−1\\
Constant Rule\\
if f( x )=C then f ′ ( x )=0\\
Coefficient Rules\\
if f(x)=c•u(x) then f ′ ( x )=c• u ′ ( x )\\
if f(x)=k x n then f ′ (x)=kn x n−1\\
if f(x)=kx then f ′ (x)=k\\
Sum Rule\\
if f( x )=u( x )+v( x ) then f ′ ( x )= u ′ ( x )+ v ′ ( x )\\
Difference Rule\\
if f( x )=u( x )−v( x ) then f ′ ( x )= u ′ ( x )− v ′ ( x )\\
Product Rule\\
if f( x )=u( x )•v( x ) then f ′ ( x )=u( x )• v ′ ( x )+v( x )• u ′ ( x
)\\
Quotient Rule\\
if f( x )= u( x ) v( x ) then f ′ ( x )= v( x )• u ′ ( x )−u( x )• v ′ (
x ) ( v( x ) ) 2\\
Chain Rule or Power Rule\\
if f( x )= ( u( x ) ) n then f ′ ( x )=n ( u( x ) ) n−1 • u ′ ( x )\\
Logarithms\\
ln(MN)=lnM+lnN\\
ln( M N )=lnM−lnN\\
ln( M N )=NlnM\\
Derivative of Natural Log\\
if y = ln(x) then y ′ = 1 x\\
if y = ln u(x) then y ′ = 1 u(x) • u ′ (x)\\
Derivative of Exponential Function\\
if y= e x then y ′ = e x\\
if y= e u(x) then y ′ = e u(x) • u ′ (x)\\[2\baselineskip]
