 Math Emeritus Sci Advisor Thanks PF Gold P: 39,691 Have you noticed that these problems do NOT ask you to find the limit but to show that the limit does not exist? That is much simpler. Here, what limit do you get if you first let x go to 0, then let y go to $\pi/2$? What limit do you get if you first let y go to $\pi/2$, then let x go to 0? What does that tell you?
