See AnswerQ: A student forgot the Product Rule for differentiation and made the mistake
A student forgot the Product Rule for differentiation and made the mistake of thinking that (fg)' = f'g'. However, he was lucky and got the correct answer. The function f that he used was f (x) = ex2...
See AnswerQ: Let f be a function with the property that f (0
Let f be a function with the property that f (0) = 1, f'(0) = 1, and f (a + b) = f (a) f (b) for all real numbers a and b. Show that f'(x) = f (x) for all and deduce that f (x) = ex.
