The limit of a multivariate function <math>\lim_{(x,y)\rightarrow(x_0,y_0)} f(x,y) \ </math> is almost identical to the single-variable limit in concept, but complicated by the realization that ''(x,y)'' can approach the target point from any direction, not just the left or right hand sides. | The limit of a multivariate function <math>\lim_{(x,y)\rightarrow(x_0,y_0)} f(x,y) \ </math> is almost identical to the single-variable limit in concept, but complicated by the realization that ''(x,y)'' can approach the target point from any direction, not just the left or right hand sides. |
