If I have the following two equations: eq1 = a1 + b1 == Sin[fi]; eq2 = a2 + b2 == Cos[fi]; It is clear that Tan[fi] == (a1+b1)/(a2+b2) but how do I get Mathematica to recoginize this? This problem is trivial, but with more complicated expressions, the answer may not be immediately obvious. Thanks, Kevin Kevin J. McCann Johns Hopkins University APL
