Problem

Symptoms: On p. 179 in the manual there is an equation that starts out f'(x) = ... In that equation there is a LIM command with h right arrow 0 underneath. Is there any way other than using the STACK command to get this? If there is, is there any way to get the h right arrow 0 part smaller than the LIM part? I know that you can use the FROM and the TO commands with the INT command to get that mathematical formula but I don't know how. Solutions: To answer the first question, yes there is a way to produce the equation without the stack command:
{f ' (x) = sub {h0} sup lim }
{f(x+h)-f(x)} over h
This equation, subscripts the "lim" to the equals sign.

As for the last question, you can produce a smaller h0, as you suggested, with FROM and TO:
{f ' (x) = sup {lim from {h0} to \ } }
{f(x+h)-f(x)} over h
This has the advantage of tying the h0 to the lim and not the =. But, the alignment is not very good vertically. You could try the following:
{f ' (x) = sup vert 50 {lim from {h0} to \ } }
{f(x+h)-f(x)} over h

The VERT will position it a little better. You may have to play with that value.
