(dy/dx)^2 tex bug?



Hi List,

I think this a bug with mactex.lisp but don't see how to fix it. Can
anyone help me out with a pointer or workaround?

Seems to be in tex-mexpt but I'm not good enough at lisp to be able to
figure this out quickly.

Here's what happens:

(C2) z:diff(y,x);

                                      dy
(D2)                                  --
                                      dx
(C3) tex(z^2);

$$%DERIVATIVE^{2}(y,x,1)$$
(D3)                                 FALSE
------- end session --------------

It seems to be digesting DERIVATIVE as it would sin, cos, atan, etc.
I was hoping for something more along the lines of

$$({{d}\over{d\>x}}\>y)^2$$



thanks for any advice!
