Hello Nathan,
Perhaps it is the following you can't remember:

> siderel:={cos(x)^2+sin(x)^2=1};
> cos(x)^2-1;
> simplify(%,siderel,[cos(x),sin(x)]);
2
-sin(x)
> simplify(%,siderel,[sin(x),cos(x)]);
2
cos(x) - 1
See A. Heck, "Introduction to Maple" 2nd ed., Springer Verlag New York
1996, pp.372-373.
With kind regards,
Helmut

sin(x)
------
cos(x)
> simplify(convert(%,tan));
tan(x)
Hope this helps.
