Use polar coordinates to find the limit. [if (r, ? ) are polar coordinates of the point (x, y) with r ? 0, note that r ? 0+ as (x, y) ? (0, 0).] (if an answer does not exist, enter dne.) lim (x, , 0) (x2 + y2) ln(x2 + y2)

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
