WebApr 14, 2024 · “@robinhanson Maybe one way to put it is that the Writing problem is that of inverting the function from text to reader reactions, to preimage the reader reaction you want onto text. A test reader only needs to know their own reactions. A writer needs to know the function and its inverse.” WebA General Note: Inverse Function. For any one-to-one function f(x) = y, a function f − 1(x) is an inverse function of f if f − 1(y) = x. This can also be written as f − 1(f(x)) = x for all x in the domain of f. It also follows that f(f − 1(x)) = x for all x …
