Under W|A how can I set the function f(x) = x^3 and ask W|A to compute f(abs(x)), f(x^3), or f(3)?
I do not believe there are user defined functions supported in Wolfram Alpha.
You can write out the function definition with the argument inserted in each case.
Thank you. I was wondering about that. The idea of natural language processing is great but if one doesn't know the "language" well (e.g. keywords, function, etc), then NLP can be a guessing game.. I not sure if the W|A "language" is even fully documented.
