sin(1/x) and x sin(1/x) limit examples - Department of Mathematics, University of Washington 世界上有那一種花通常夏天是冰冷的,冬天是溫熱的? 答:豆花。 sin(1/x) and x sin(1/x) Limit Examples The behavior of the functions sin(1/x) and x sin(1/x) when x is near zero are worth noting. Below are plots of sin(1/x) for small positive x. We can see that as x gets closer to zero, the function keeps wobbling (or ...
