"find limit" of function questions, i see it in two forms, i want the difference in meaning and also in the solution method for each, in details please.

First:

question say that the function [tex]f(x,y) = x^2 + y[/tex]

and want me to find the limit of function [text]f(x,y)[/tex] when [tex](x,y) \rightarrow (0,0)[/tex]

also want me to see if it is continous, and the detailed prove for the two previous requests.

Second:

question say that the function [tex]f(x,y)[/tex] has two values,

1) [tex]f(x,y) = x^2 + y[/tex] at [tex](x,y)\neq(0,0)[/tex]

2) [tex]f(x,y) = x[/tex] at [tex](x,y)=(0,0)[/tex]

as mentioned above, i want themeaningandsolution method( get limit and check continous. ) andproof.for the two cases.

waiting for replies ..
