Just a trial.

$\displaystyle x^2+y_1+z_(12)$

$\displaystyle d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h
$



so sorry.it is just a trial.

how to input the theroms?

[quote=fivestarswoo;463120]`x^2+y_1+z_12^34`

$\frac{d}{dx}f(x)=\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}$



so sorry.it is just a trial.

[tex]\frac{d}{dx}f(x)=\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}[/tex] gives the correct result.
