I'm sure there's been no end of jokes about you sending each other French letters.
When my oldest sister was doing final year high school French and Dad travelled to France, he sent her six foolscap pages hand-written in French... we used to refer to when he sent his daughter a French letter. He had an impressive memory.
If you're into buying stuff, Mathcad with the symbolic toolbox is very nice. Mathcad uses Maple, as does just about any for-pay mathematical program that includes symbolic manipulation.
Maxima is kind of the gold standard for open-source symbolic simplification (I think it's where Maple comes from), but it's text based, doesn't know how to reduce units (unless you do extensive coaching, I suppose), and can hang up on trig problems. Of course, I've also just described Maple...
Whether Maxima or Maple is the underlying engine, you'll often find that the "obvious" simplification you're looking for is just not coming out. In that case, you can often get a long way by making a guess, and then asking
VERY OFTEN, when Maxima can't reduce something to my taste, it'll still correctly cough up 0 when I do the above (and when I've gotten my reduction right).
Habib, Just ignore DecadentLoser... he's just that, a total loser... and ignorant to boot.
I'm of the (very) old school... I had three years of Latin in High School and one year of French... my wife-to-be and I communicated in French when I was at MIT and she was still in West Virginia... to thwart her mother reading our love letters ;-) ...Jim Thompson
