statement: “For every 8 >0 there is an e > 0 such that if 0 < 12 - al <8, then f () - 11 < E." Show that this statement is not equivalent to the statement limete f(x) = L by letting f(x) = sin 1/x for 2 7 0 and a = 0. (Hint: For the special function f and a, which statement is valid, and which statement is not valid?)
