 Author Comment/Response Forum Moderator email me 03/10/13 6:55pm In the current 9.0.1, I got In[3]:= Solve[K == Sqrt[(M - 1)/M], M] Out[3]= {{M -> 1/(1 - K^2)}} Version 5.2 solved it, too. Since Mathematica is used a lot for creating large programs, it has to be more literal. Wolfram|Alpha makes assumptions to make easy calculations easier. Solve is oriented toward polynomial equations. There are some extensions. Since Mathematica built-in names begin with capital letters, we recommend that user names begin with lower-case letters. Clashes can produce odd results. In[1]:= ?K K is a default generic name for a summation index in a symbolic sum. In[2]:= ?M Information::notfound: Symbol M not found. >> URL: ,
