Hello,

I recently encountered this problem. I wanted to solve a not so complicated equation:

Solve[K == Sqrt[(M-1)/M], M]

Mathematica returns an empty result set.

Doing so in WolframAlpha, the result is M = (1/(1-k^2), which is correct, of course.

In both programmes, I entered the exact same code.

One could think that a quite expensive Mathematica can handle at least what WolframAlpha can compute ... but here it seems not to be the case.

Any ideas? Did I do it wrong?

Best regards,
Tobias
