W|A input "tan^-(1*2)(x)" does not equal "tan^(-1*2)(x)"

As for the two inputs, I would regard the resulting W|A interpretation of the one with the link as problematic.Possibly a parse issue in Alpha.

I fail to see a reason to reject either, though. Among other things it would involve solving a very difficult problem: determining what was NOT intended. Probably not a good path to go down in any case.

I'm not sure about WolframAlpha as I rarely use it, but in a traditional Mathematica notebook the two forms of the input expression evaluate to the same thing (see below). enter image description here
