My windows version (2.2) gives the same result to both commands. JTW2 at NIOSR1.EM.CDC.GOV ---------- >Subject: [mg1772] Bugs with transcendental functions? I have two similar equations listed below. The 1st one came out OK, but the 2nd one didn't go anywhere. The only difference is "p" in the 1st one is replaced by "a" in the 2nd one. I'm using mathematica 2.0 on NeXTStep 3.0. Is it a bug of the version of MMA I have? 1. Input:= Solve[p (-Log[x + a z]+ Log[ w + a z])/qq== y, x] Output:= w + a z {{x -> -(a z) + ---------}} (qq y)/p E 2. Input:= Solve[a (-Log[x + a z]+ Log[ w + a z])/qq== y, x] Solve::tdep: The equations appear to involve transcendental functions of the variables in an essentially non-algebraic way. Output:= a (Log[w + a z] - Log[x + a z]) Solve[------------------------------- == y, x] qq
