sin(1/x) and x sin(1/x) limit examples - Department of Mathematics, University of Washington 怕一個人去吃迴轉壽司遭異樣眼光嗎? 沒關係,一個人在家也可以吃旋轉壽司!!! 怎麼會這麼好笑......XDDDDDDD 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 ...
