Homogeneous nonlinear function

[quantster]

So if i declare f(x)=x^2+y^2, and then declare g(x) to be the square root of f(x), in what way it that not sqrt(x^2+y^2)?

Very intereting posts and emotions. To be consistent with the original notations of matt, he could have written g(x) to be square root of f(x,y) and not f(x), as he defined f(x,y) and not f(x) to be x^2+y^2.

I was not planning to write but quantster raised a good point. In fact that was the beginning of the confusion.

In the future make sure to use consistent notations instead of assuming that people shall get some vibe from you and be able to read your mind.
