Suppose that u(r,)=sin(rcos (0)). (a) Find (b) Find or (c) Find Wor (d) Find u Br x-1 1. (3pts) Consider the function f(x,y) = x1 3, (x,y)(1,1) 2. (2pts) Give an example of a two variable function that is not continuous at (1,2). Explain why your +y, if x1 if x=1 Find lim f(x,y) or show it does not exist. example works.
