it seems that i dont have a clue how it works. maybe some of you could explain it to me that i can pass the exam tomorrow,
Do you know what "fix square" would do with other argument values? If not, it would be worth your while to look at a whole lot more arguments because the results could be illuminating. Also, try replacing "square" with some other functions like "id" or (\x -> x - 1) respectively. Consider the value of the expression abs(f x -x) <= 0.01 if the function parameter "f" is "square". What values of x would produce a True or a False result? You'll find a close relationship between this question and the result of evaluating "fix square ...".
