Unfortunately you can't! Only the response has the plugin to display sybols.
But you can make it easier to understand by using correct syntax with plenty of parentheses. For example, if you want `int sqrt(x+1)dx - 4` , you should write
int (sqrt(x+1) dx) - 4
"the integral with respect to x of the square root of (x+1), minus 4"
int sqrt x + 1 - 4
When in doubt, add extra parentheses. A few reminders about what symbols mean what:
If you're more ambitious, you could copy and paste symbols (like √, ∫, ∞, etc) from unicode, though this won't help with exponents or fractions: http://en.wikipedia.org/wiki/Mathematical_operators_and_symbols_in_Unicode
Also, you can also go to textify.com, get your expression looking good, then copy and paste the image link into your question body, something like
But this takes a little getting used to unless you're already familiar with Latex.
You could also paste a link from wolfram alpha, something like http://www.wolframalpha.com/input/?i=f%28x%29+%3D+integral+from+0+to+x+of+%284t+-+5%29+dt
Anyway, I hope this helps clarify your options!
