Find all boundary points
S={(x,y); 0<x<1 and y= sin (1/1-x)
I dont understand can someone either get me started or tell me how im supposed to solve this step by step. I know that the definition for boundary points is that if u can draw a circle of very small radius then there are points in that circle that are both inside and outside the given set. what i dont understnad is how im supposed to know every single boundary point. Please help very confused and frusterated.
