Here are some ideas that should help:
^
" to represent superscripts, as in "x^2
"
for "x squared", and "x^(1/2)
" for "the square root of
x". Use parentheses to avoid confusion about what belongs in the
power. E.g., "x^(2n)+1
" rather than "x^2n +
1
(x^2)n + 1
x^(2n+1)
_
" to represent subscripts, as in "x_i
"
for "x sub i". Use parentheses as above to make more
complicated subscripts clear.
2x^2 + 3 = 1
2x^2+3=1
"
/
", as in "(x+1)/(2x3)
",
not "x+1/2x3
" since this could be read as "x +
(1/2)x 
3
I can't figure out how to factor the equation x^3  2x^2 + 1 = 0 Can you give me any advice?
1 f(x) =  1  x 1 so f'(x) =  (1x)^2
$
" for the integral sign, and use superscript and
subscript symbols to give the limits. E.g., "$_0^1 x
dx
Another possibility would be to use "I
" or
"Int
" instead. For example: Int_0^Infinity (1/x^2)
dx
There is no standard for this, so we will try it out and see what we like best.
lim_(x > infinity) e^x
