I love to cook with wine. Sometimes I even put it in the food.

tan(a) + tan(b)
tan(a+b) = ----------------
1 - tan(a)*tan(b)

I think your only hope is a numerical approach. I suggest you state the
problem in the form: a = fa(x, y, p), b = fb(x, y, p) and post your query on
the SciPy newsgroup: http://scipy-central.org/.




I thinks Hobbs' move satisfies the Algebra. I'll report back later...
this is all about behavioral modeling/curve fitting.
